Racking up passport stamps has never been easier—and you don’t even have to leave the Front Range. Plunk down $20 on a Denver Passport, the brainchild of the boozy minds at Imbibe Denver and Denver Off the Wagon, and spend Memorial Day through Labor Day sampling some of the city’s best cocktails. Flip through the booklet and pick any of the 60 participating bars and restaurants (think TRVE Brewing, Ste. Ellie, and La Biblioteca), ask for the drink special listed in your passport, and you’ll nab two for the price of one, plus a stamp. Bonus: In its second year, the program has expanded to Boulder and Fort Collins.
