I will be taking a plane trip to another state very soon. The trip will be 4 hours, and I will have absolutely nothing to do if I don't bring my Nintendo DS. This would normally not be a problem, however along with my DS I will be bringing my TTDS with a 2 gig microSD card with a lot of questionable data. I was wondering if it would be a good idea to do this.. I'd just hate the security guy to actually know what a TopToy is and be all like "WTF IS GOING ON HERE!?!?!?" If anyone could provide some insight or talk about their experiences taking a DS w/ a flashcart on an airplane, I would appreciate it very much.
