A very good friend's son, 22 years old, cinema major, is planning a road trip from Chicago to Mexico, thru Mexico, and hitting Costa Rica/Belize and then coming home. He's going with 4 other non-hispanic guys (although one speaks a litte Spanish) to film a documentary. He's an inspired young film maker. Everyone is saying outright "no" to this trip but is there a way that you can be relatively safe in doing this? I totally understand the allure of this trip.
