Probably the two Fast Draws (sold one, still have the other). They were pretty close to each other in Canton, OH. Unfortunately, I bought at different times. So about 600 miles round trip. Most of other EMs were Detroit (240 miles r.t.), Chicago (300 miles r.t), Grand Rapids (120 miles r.t.) and Kalamazoo (20 miles r.t.).
Compared to getting my Safecracker at 1,600 miles round trip...pretty close I'd say.
Yeah 10 hours is a stretch. But sometimes the fun of this hobby is the time spent driving with a friend to get a game. Sometimes it's about the journey and not always the destination.
