I drove through this area as well yesterday afternoon (Pembine - Dunbar - Florence) and saw a lot of the same trail crossings that mike posted pictures of. As I told me parents afterwards, at this point I wouldn't expect great conditions for an entire day of riding, but a nice 60-80 mile shake down ride is completely realistic, especially if you stay on trails that get groomed throughout the summer (ATV trails). In this sense, the best trails I saw were those on summer groomed forest roads and the RR grade west of Florence, the worst trails were those in ditches or swamps that are not used in the summer.
