Round One of the NBA Playoffs is under way and fans everywhere are stamping their Gowalla Passports when they check in at arenas for playoff games. This is your chance to add the Lakers, Celtics, Cavs or Mavs stamps to your Passport by going out to support your favorite NBA team!

If you’re new to Gowalla, it’s the best way to record and share the places and events that you love with friends and family. Be sure to sign up for your Gowalla Passport, then grab Gowalla for your mobile device (like D-Wade’s MyTouch 3G!).

Gowalla makes it easy to upload photos, share comments with your friends, then find a great place to meet up for dinner or drinks after the game. And stay tuned as we head toward the NBA Finals. There’s more to come!
