I started playing Roundnet (AKA Spikeball) after seeing it on Shark Tank and have fallen in love with playing it. It is like a mix between doubles volleyball and foursquare. What's awesome is that it can be played anywhere: hardwood, grass, sand, and cement. It's popularity is starting to grow but not so much in the bay area (excluding San Francisco) so I decided to make this meetup group to see if other people are interested. As of right now I have 3 sets so it will be max 14-16 people meetups (unless someone else has one we can increase it). They can be purchased online at http://spikeball.com/ ,in-stores at Dick's sporting goods, or from me for $15 cheaper.
