Pouring money into my truck, and I really want to show it off, hoping there is a trip coming up soon so my newb member status can be changed tp member 310-989-6826 hit me up for any runs.
Keep an eye on the Xcursion Forum, but I don't think you'll see many 3-5 day trips. The (usually) 3rd weekend of the month club runs are generally 1 to 2 days long. Paul or Brian may set up a 2-night Mojave Road trip in the Spring, and maybe Bradshaw Trail before that, which could easily be a 2-night trip.
If you want to set up something longer you would probably be better off researching something yourself and then asking if anyone here wants to join you. Hint: the more information you provide the more likely you are to get someone interested. There are lots of good guidebooks mentioned in the Xcursion Guidelines posting that you might find helpful.
If you're looking for ideas for longer trips, maybe someone here can suggest a few trails. If I were going to spend a few nights out this time of year, I would probably think of the Bradshaw. Even that might be a little cold at night though. You could easily spend several days wandering Death Valley, but be careful of snow on the way out. Once Spring gets here there are several more options.
Just a few thoughts - I'll leave the rest for someone else.
