I have been trying to ride my bike in the snow for 40 years. Fat bikes have become a game
changer for me in the snow. Do we all have fat bikes in this discussion?
Same here. I had an Elgin and Typhoon before original StumpJumper.
I share a Farley bike with my wife. If trails are solid I'll ride an AM type bike with pretty fat for 26r fat Hans Dampf tires.
Trust that I totally get the desire to mandate the right tires. Our real fat bike really is best but there are times when we can have a family ride or I can ride with non-fattie friends if it's not all fat tires. More important is where I sit with land managers, trail stewards and also on the Blackhawk board of directors. We're all better off with fewer rules.
Standardizing on signage and education that in essence says don't leave marks is probably our best bet. It will work for all seasons. Our logo and address on the signs will help.
Sharing ski trails might be a place where true fat tires would apply. That's a bit premature. We have some shared trails at Pleasant View. Our land manager there pointed out there was a day when no one wanted skis on a golf course, then a day when classic skiers didn't want to share with skate skiers, she smiles, and says she hates it when user groups don't get along.
