Chevy - You're arguments are weak. A highway is required to have signs for every turn, bridge, bump, etc. If your wife set the cruise at 60 all the way home, she would be the closest comparison to Ricky Racer. I highly dought your Tahoe would handle those conditions at 60mph while she sailed home. She would have been off the road and, possibly, taking someone in a Focus with her and into the trees.
She rode as conditions allowed and I will bet you she looked for every sign to warn her of what was coming up ahead. The same should apply to the trails.
Let's keep this in perspective. Roads, trails, Tahoe's and snowmobiles are the farthest from true comparisons you can make. Regardless of "conditions"!

Comparing roads & cars to sleds & trails makes no general sense not apples to apples in pratice. Removing bridge ahead & narrow bridge from snowmobile trail signage is not acceptable to me. Some of the others that they plan to remove I can deal with but 2sleds in opposite directions meeting on a snowmobile bridge is as dangerous as it can get. Removing these signs as part of the new plan without any other warning sign to replace them is just not discreet & very dangerous. You have no place to go on a brigde no way to bail if you meet head on traffic no way to know a bridge is ahead on the trail. This is dangerous for every rider as speed has nothing to do with it a bridge is a trail hazard & all riders need these warning signs to know a hazard is ahead.
