Me...

You would think I would have known better. I had a nice new bag from LL Bean..perfect size, carried it messenger style. It had a nifty pocket right under the flap that was perfect for my AP and room key. Well, I had to have my AP reissued at least three times in three days!! And my dd's as well since I carried hers with mine. When I got to AK I finally lost it...just went over the edge. My AP wouldn't work (yet again!!!) in the scanner. The CM politely asked me if I had carried it near any magnets, cell phones, cameras etc. No, of course not I told her. I know better, I'm not an idiot!!!! Yep, that's what I said..I'm more than embarrassed to admit. Anyway...as I, once again, approached Guest Services to get yet another AP, I remembered what was keeping my nice, new bag shut!! A huge magnet, on both the bag flap and the bag body!! Duh!! I was mortified. I did go back to the same CM and apologized profusely. Told her I was an idiot.
When I got home from that trip, I took an exacto knife and cut out the dang magnet...replaced it with some nice, non-offending Velcro!!!!
So, yes, it happens even to those of us with many trips under our belts!!
