Despite a lengthy briefing of the area using maps and Google Earth, Lisa and I managed to immediately end up in the forbidden "Bermuda Triangle" area.  When we got back on course, we followed a dune buggy that looked like mom and Katie's. 

It wasn't. They were stuck at the top of the highest dune, wondering why we'd left them high and dry. While Lisa and I were on the long trail to the beach.  

We all had great fun. But if there's ever a next time, I'll definitely need to do a better job of paying attention to where my fellow sand surfers are.
