Had too much free time and I was bored out of my skull, so when pair-flying partner John Mittel (BZ) commented that he was having trouble finding a decent glider logging program that would process IGC files, I decided to give it a whirl.
Thirteen revs and a broken friendship later (just kidding about the friendship!), I think I might have a usable program. If you are interested, see the Soaring Cafe article about it at
