The more polite sectors of society might frown upon alcohol consumption before 5 p.m. But what if you combine it with physical exercise and an essentially green activity? That kind of virtuousness cancels out the points you lose for the day-drinking, right? Good thing we have the Beer Snob Bicycle Pub Crawl, an occasional Saturday group ride, usually through South Beach and downtown, that cancels out the perils of drinking and mass commuting in one fell swoop. Join your fellow two-wheeled warriors from the afternoon to early evening for a tour of fine establishments that are not only bike-friendly but also wallet-friendly. Stops on the circuit have included sudsy SoBe staples such as Zeke's Roadhouse on Lincoln — where everything is $4! — and the Abbey, as well as newcomers on the mainland, including the DRB, Elwood's Pub, and the Filling Station. Zip past all the car-driving losers burning gas, stuck in traffic, and blowing money on parking, and use the cash you save for an extra brew. And hey, let's be real — there's a lot less of a chance of getting a pesky DUI. Still, the organizers of this informal jaunt would rather the complete scofflaws stay at home. If you want to get down on this ride, you'll have to drink responsibly, bring a bike light, and obey all traffic laws — this isn't Critical Mass, so there's no corking of traffic. Other than that, sip and enjoy. Check the Miami Bike Scene blog for upcoming dates.
