Participants pay a $20 registration fee and then make their way around several Grove bars where they'll enjoy drinks and food at a discount. Rodriguez and Ruiz hope to raise $5,000.
Registration starts at 2 p.m. and drinking begins at 3 p.m. at Mr. Moe's Restaurant and Bar. The registration booth moves with the crawlers every hour so you can join in at any point.
