The Middle Fork trail is a great hike right now. There are a few stream slide outs that you have to get through but nothing unreasonable. I did the stretch from the Gateway bridge to Dingford Crossing and it was great. Get out and enjoy!
BTW: The worst stream wash out is the first one you come to. The pink flags are a little sparse, so work your way across the sand and rock and remember the trail out is about the same level as the trail in.
