A few new trails that I have nothing to do with that need mention. 504 trail now links 505, 506 and 507 with a bypass for all the hills. A 2wd truck should be able to follow the bypasses as far as I can tell.
On the Big Hill Bypass, there is a trail system named Area 51. Lots of small hill climbs that are continuing to pop up. I think there might be 5 or more lines now.
Tyler is in the works of tying more trails together to make longer loops, with multiple outs and bypasses for tougher hills and basically helping to make the park easier to navigate. I applaud his efforts and the staff. They are moving this park in the right direction. I have a few pictures, but my phone is acting up with Tapatalk and will try and upload them in the morning.
