I've been the last 5 years or so. I highly recommend going to the Jeepers Jamboree, especially if its your first time on the Rubicon. Its a fun time and all your food is taken care of, good food too. I dont know how old your son is but there is a minimum age requirement, it think 16 or so. Its more of an adult party, there is a bar and lots of drinking. If your looking for more of a family environment I think Jeep Jamboree is the way to go but I'm not too sure.
Also, we are thinking about doing a Poly Performance JK rubicon run in June, if you want to attend that your welcome too.
Those of you that think you know everything really annoy those of us that do!
