We ran Billings for the Rock Junction trip in June and with a 8am meet in town we were done and back early in the afternoon, I think around 2-3pm? Group was 10-12 rigs, mostly smaller jeeps but all moved along pretty good and just had fun, nothing major happened.
There is a large parking area on the top of the hill at the Bangs area trailhead where we can leave trailers and it's all dirt or slow asphalt from there.
With a 9am meet up near the interstate, we need to be ready to leave at 9am and ready to get in the rigs and roll from the parking lot when we unload. It's easy for me to spend a while transferring from tow rig to trail rig so I'll have to work on this one a little ahead of time.
Be prepared for some suck-y-ness for the tow rigs on the road up there. It's a steep hill and twisty enough it seems like I'm always between gears.
It will likely be HOT there, be prepared for that and make sure you have some bug spray, the gnats can be bad up there. Pants and long sleeves are not a terrible idea. I have no idea how they'll be this late in the year, I've only been on the trail in June.
I took our UA truck through on my last trip and had to work a little to keep it straight and thought a couple times that it was nice to not have to worry about tail lights. Pretty much everyone will use the winch so be ready for that. All in all a good fun trail.
I'm hesitant to change the main meeting place but if the guys that are staying on the south side of town (KOA, etc) want to meet at a secondary location that's fine with me. We can pull through the albertson's at Monument and CO340 and meet extra people there without everyone having to drive across town twice.
