Few quests are as fun as the search for the best taco. Add a bike ride to the mix–which is what the bloggers behind Brooklyn by Bike have planned for their fourth annual Tour del Taco this Sunday–and you have an adventure and workout in one. The donation-based ride supports The Youth Farm at HSPS, a project of BK Farmyards, and starts at 11am at Grand Army Plaza, travels south in Brooklyn, north up through Queens and ends back in the BK. Register here for the taqueria joy ride.
