Rozarks is open and currently most of it is in great shape.
There is one pretty bad spot on the upper line between MtMarty(below the arch) and Fisher park. We plan to do some work on that as we already tore that spot up with the race last Sunday, so I am not worried about messing it up. You can ride through if you want, but as an alternative, if starting from Fisher Park, you can ride down the powerline cut to the deadend of Cherokee St and then climb the switchback from there into Mt Marty park, and reverse. I did that last night without issue. When entering from Fisher, go right across the first bridge then stay left down into the powerline cut. See map:
The bad line is the one to the right of that. We plan to do some rock work and repair to make that area more ridable in marginal times, since most of Roarks has been ridable for a while.
Also, between Fisher Park and Minnie St there is a new lower line we opened this month(not yet in google, which is otherwise up to date) which is pretty fun with some dips and climbs in contrast to the flat existing line through there. It is fully ridable and only needs a few minor touch-ups.
