This is one of the few reasons I wished I still lived in Sandy Eggo. Here in Sticks, MS there is next to nothing out in the wild. With the few exceptions of business trips, I have to essentially collect whatever I want to play, or visit a local fellow collectors collection. A recent 3-day trip to Sandy Eggo and I was able to play TSPP , IJ4, Avatar, Tron x2, TAF, T3, TFTC, AFM x2, X-Men Magneto, & MB. It was an abundance of traffic and lack of time that kept me from playing MM, DH, CV, and a couple others at another venue. And I still managed to squeeze in a couple client meetings.
Of course, if I still lived in Sandy Eggo, I'd probably not be able to afford a house in which to collect pins.
