heh, The first time we camped at buttercup I didn't know that the border road (kind of a mini sand hwy) was only 50 yards behind our camp. I took off in my truck to romp around the sand a bit and went onto the Mexico side about 100 yards in. I had more damn border patrol on my ass than I knew what to do with, 1 truck from every direction surronded me! I was like WTF? A couple of em came up to my truck, one guy was like " Hey man, this is Mexico! there's fedarally, Mexico Police and some people you want nothing to do with, you can go over here if you want, but I cant do nothing for ya once you cross the border. We get smugglers and coyotes through here all the time" So I stayed clear of the Meceeeco side the rest of the weekend.
