This is easing away from the OP's initial question of cost of the sport, but I have been thinking more and more about the future of the sport. Kinda important to this site.
Anyway, when I was introduced to snowmobiling as a young lad in the mid 70's, sleds were fairly inexpensive and almost disposable, a lot like the autos of the 70's. Folks that lived outside of areas that had consistent snow (basically south of a line from around Brainerd to Rhinelander to Escanaba and then much of lower MI outside of the LES belts of NWL MI) did not have to sacrifice as much financially to get into the activity then as they do now. As a result, there were much more households that owned snowmobiles- even though they might only get to use them once or twice in a season. They were perfectly content to use the sleds mostly locally, hopping around in 10-20 mile trips. Occasionally, a trip up north was made specifically to snowmobile, or perhaps folks kept these sleds at their vacation home up north and really only used them there.
Fast forward to the 80's and 90's and sleds started to become more technologically advanced. More comfortable to ride for longer periods of time. More reliable to ride for longer periods of time and also more expensive. This cause folks to feel like they should get the most from their investment, which resulted in more trips up north to where the snow was. Folks still rode near home, but just not as often.
Jump ahead to the current day and sleds are enormously expensive, highly advanced technical machines. Very few that buy them buy, do so to just putz around their local neighborhood when there is snow on the ground. They want to maximize their investment by traveling to where there is consistently good snow and a trail network which will allow them to travel great distances (including across multiple states in one trip) in a 2-3 day period.
This has put more and more pressure on the trail systems in the north, but also been good for locales/businesses that have the reliable snow season after season.
Unless manufacturers figure out how to make reliable, but low-cost sleds, families will be dropping out of the sport more and more and the trend towards groups of 3-8 friends all having sleds and planning trips to areas considerably far away from where they live will grow.
Down the road, I can see a lot of the trail systems in the central Midwest going away. It will just not make sense to go through the trouble to get easements, sign, maintain and try and keep landowners happy. The focus will shift to the areas that receive reliable snow (including the mountains). In order to survive, they will need to go from being grassroots type clubs to organized "businesses" that are 100 percent responsible for everything that needs to happen to have safe and fun trails to ride. These "businesses" (I use quotes because many may be non-for profit) will be supported by the local businesses that receive money from the snowmobile tourism.
I doubt that this will happen in a quick manner, rather more like a slow crawl. Everyone will have their own opinion if this is a positive direction or not. I also do not think that there is a single demographic to blame. From an owners standpoint, who does not want a better sled to ride? Even if it means an increase in price. We did not go from new sleds costing $1500 to $15,000 in a few years, it took 30-40 years to do that. From a manufacturers standpoint, they were only trying to follow where the trends in the activity were going. That is their goal.
In my opinion, snowmobiling has always been a "nitch" activity. Perhaps almost mainstream like boating is now back in the haydays of the 70's, but it has never been a mainstream activity among the general public. If the trend continues, it will become more and more of a nitch sport. The number of sled owners dropping, as well as the amount of trail systems. Those systems that get reliable snow will figure out ways to do things better than they are now and will become the place where 85-90% of the snowmobiling is done. The sleds will continue to get more and more advanced and more expensive, but the cost increase will slow like the auto industry did in the past 5-7 years.
So what do you all think? No way, no how, or "Hey that goofy looking guy in the corner might be onto something"?
