heading to west yellowstone for 3 days riding in the beginning of feb. planning one day in park , two days out would like to put together some scenic long rides at least 200 miles per day any suggestions . guide necessary out of park? are trails marked well? maps available? I can get around fine with a map but sometimes here in the northeast things arent marked correctly i want to be able to find stuf like two top etc. are trails wide and fast or twisty turny?
