Posting your ride results on a thaw day can sometimes be a bad thing, if you don't indicate the trail conditions. Fat tires can do some damage in deep sloppy mud, but I doubt yesterday a Pugs would have done much damage. I was at Olson's yesterday and conditions were firm until about 2:30 when I started seeing some slush. It's easy to make a quick exit on that trail, but wasn't necessary as I made my last lap on the firmest area.
In soft conditions a 2.3-2.5 MTB tire can look like a Fatbike track. Even more so if they are using 45-50MM wide SnowCat/trials rims. Now that more Fatbikes are out there, be ready for the bogus claims we're out there riding in every condition. There's a certain group of rider's that frequent ILRA every year and they constently ride when they should not. Some of their tracks are as wide as a Larry or Endo.
Seeing the time Barry007 made his post tells me he had to have been off the trail at the right time in order to return the bikes and get home, but Dave makes a really great point - if you rent a bike from any shop, make sure you indicate the conditions you post about if you give the shop a plug, especially on a day when conditions start thawing. You could make the shop look bad. Keep in mind what I said about the 2.3-2.5" tires, if some knucklehead rode afterwards and made some nice fat ruts in the trail, guess who gets blamed? Not everyone is familar with a Larry or Endo tread pattern, they just see wide tracks and make an assumption.
