actually, I had a very similar experience last week at my local ACE. They're going out of business, so I'm always over there "stocking up" on the 50-75% off fittings and pipe. With some spare parts in hand, I ask a guy working there for 5ft of 2" and a few feet of 3". Thinking I was making a basic gun, he exclaimed, "You know, you're the third person this weekend to come in for potato gun parts!"
I was pretty surprised, as I don't know and have not heard of anyone around here making any spudguns! It really puts into perspective how big even a place like Nashville is...
I really wish there were some fellow spudgunners in my social circle, however.

Its depressing to be the only person I know who builds potato guns in the Middle Tennessee area...
