Got a tip about this from another thread on here a few weeks ago. I used it last weekend to plan where to go in WI and it was great to check out trails around cities and look for hotels, drop points etc. Didn't use it on the trail, but would expect it to work great.
Only question I have is why are very few trails shown in IL, IA and IN? I know of a lot of trails around Rockford that I ride into WI and they aren't shown in IL, but are there at the WI border. Doesn't really matter, I only ride once or twice at the most down here anyway.
Also, wish they had trail numbers shown, but to the best of my knowledge they don't unless its a layer I haven't found yet.
