Dave Grohl Alley is one of those Atlas Obscura roadside attractions you just can’t help but visit. Tucked away behind a Burger King, it is literally an alley dedicated to drummer Dave Grohl, who was born in Warren. Evolving since 2009, it is a showcase for local artists, and worth a stop if you find yourself in the area.
Modern Methods has a tasting room off the alley, and serves several good sours. Warren itself has several other architectural interesting buildings, including their Richardsonian Romanesque court house.
