The thing that really just gets me mad is that these folks probably go to events with the sole purpose of stealing. I'm sure they walk around again and again looking for the perfect chance to snag something.
One tiny bit of comfort is that if someone is doing what you describe it's fairly easy to notice. IFF you're inclined to notice it. It's terrible that attending an event with collections like some posters on these boards have requires constant vigilance and at least a hint of paranoia, but it's still the case.
I hope they catch these guys and get everything back.
@rcwraspy I went to the LGS in my town today. I haven't gone out of the house to play Magic in ages (I had quit for a long time before 2013 and have mostly played MTGO since). My son (age 5) needed me to take him to the bathroom. Without hesitation I walk him to the restroom and wait inside because he's nervous in places he's unfamiliar with. I then realize I've left all of my valuable cards out on a table unattended. Nothing happened, and I didn't think anyone at the shop would mess with my stuff, but I realized that in this day and age letting your guard down like that is a recipe for disaster.
@Islandswamp Yeah man, its crazy. I won't even leave my stuff in the car anymore. Whenever we do post event dinners and such the bags come into the restaurant.
I've become more cautious with my stuff too. I just don't want to have this exchange with the officer, "Yes sir. The box that was stolen is worth more than the car that it was in. No sir, I'm not joking."
100% why I'm selling out (again, and this time for good). Cards have become so valuable that they are a liability to travel with (or even to have them in my home). If I am only comfortable keeping them in a safe deposit box, then what is the point? I'm 100% arena/cockatrice/proxy now.
