Passport Adventure

Visibility of sponsors will be enhanced through the Passport Adventure program, a fun challenge for guests that encourages them to fully explore the Block Party. Each sponsor is given a stamp to mark the passports of guests who visit their booth. Guests whose passports are completely stamped and turned in are entered in a drawing for a variety of prizes.
