Footbag is basically the best sport ever. It's portable. It's a great workout. It's challenging even after many years of playing. And it has a great community.
I kicked with Kaiser Ahmad and Scott Bevier at Penn State many years ago. Then I moved to Athens, Georgia and kicked with Ben Scarborough and Andrew Coleman, and occasionally with Dave Holton. Then I moved to NYC and had a great regular shred circle with Matt Isanuk and David Sussillo for 5 years. Then I lived in Montreal for a couple of years. I practiced solo for most of that time, although I did manage to kick with Ianek Regimbald, Mathieu Gauthier, and a few others on occasion.
