This summer I'll be heading down to Baja with a couple of friends from mid-May to whenever in August when I (hopefully) start med school. It'll probably be the last time in a long time that I get to make a trip like this so I want to make the most of it. One of the guys I'm going with has a two wheel drive 4runner, but we're thinking of upgrading. The idea would be to have everyone pitch in and get an older 4x4 Explorer to take down then sell it off once we get back. How necessary is it to have a 4x4 in southern Baja? Is it really going to be worth the effort? If it can get me to remote areas where we can post up with less crowds it would be, but if the sand is such that only ATVs can get to the really out there places then I'm not so sure.
