Took me forever to get thru Boston security cause of the stick. Granted, I had it in it's case, with an atty on it, and spare loaded atty/carts on each side, so it may have looked a little weird when it was scanned. Even after they took it out, and I explained to them what it was, they still took it back thru x-ray twice, and called the other screeners over so they could see it. Don't know if it would have gotten all the attention, if I didn't have a herd of attys hanging off of it. The interesting part was that I had my little travel case with a whole array of 510 batteries, attys, carts and a couple glass dropper bottles of juice (oops..forgot to take them out), and it went thru without a word. Go figure.
