@mattybfat That case with Allamuchy can be considered for a number of trail systems.
That's the same idea that is used with trail forks.com (avoiding driving there). You can go on to a riding area on trailforks.com and see what conditions are like...just like this new system on this site except with more detail. I have to drive over an hour to all of the good locations so I also want to know if it's ridable. The problem is, with any of these system, is that people have to use them consistently. Trail forks.com should be adopted by all of the JORBA park reps as it offers a lot of features to log work that is done in the parks as well as so much more. All of this info can help the mtb community....as long as people use them!
As an example, Wharton is currently listed as 2.5 but I've already heard from people that say it's ridable. I rode last weekend out there and there was a low lying area that was muddy...do I rate Wharton as a 1.5 on this site because of the mud in one spot? I also encountered impassable puddles that were 3" deep on the green loop, so again how do I rate the park?
If you go to trail forks.com and go to the Wharton riding area you can quickly see conditions and avoid the green trail.
