GPS and Airline travel in General geocaching topics Posted August 17, 2007 This discussion is already taking place on page one in this thread. I'm normally not someone who markwells someone to the previous ten times we discussed a topic in here, but I do think one thread a week should be enough? My bad. So sorry to do a forum mistake. Just getting back into geocaching and trying to get info. I'll just read every post from now on. Thanks for the info about carrying on. I'll do that. Looking forward to Philly!
