I remember riding in the yoop back in the early and mid 90s, and they were nowhere near as accepting of snowmobiliers up there, as northern Wisconsin was. Even when I lived up in south range, many older locals really disliked "bubbleheads"....the perception was that we rode loud, stinky machines, and were a bunch of drunks. The trail signs were written on carbboard boxes with sharpies, and grooming was not very good (bumps the size of volkswagons on the Nichols trail). Gas stations were closed at 10 PM, and there were very few warm up stops, to get something to eat.. What people need to understand is the yoop is not part of northern Wisconsin...the culture, heritage and the people are different. Winter is very long for the locals who live up there that don't snowmobile. Snow is something they are used to, but also hate. (you would too if you didn't ride, and had to shovel 300 inches a year)
That being said...things have changed through the years..the clubs up there really picked it up...they groom better, they mark trails better...there is better lodging, and places to eat, and I have noticed a much more accepting attitude towards sledders. But i remember when I first moved up there..being from Wisconsin, they didn't accept me at first. (Sorta the same thing as what Illinois people are treated in wisconsin, you're an outsider). The one thing we did have in common is the packers (though I found out it's closer to 60/40 Packer/Lion fans)...they love their hockey up there, and have awesome high school programs (and of course the redwings)...they follow the tigers in the summer (not the brewers)..but figuring out what college team they follow is tricky...lots of michigan state fans up there, but also alot of Michigan fans (and neither of those fans like the badgers).
You will know you are accepted by the locals up there when they invite you over for a Sauna, or a Mojakka cooked over a wood fire...and becareful drinking any Yooper Coffee (they make it really really strong...like at PATS...right Kip???)
