It’s a great walk. Beginning where David Lee Roth, way after leaving Van Halen, was busted trying to buy a $5 bag of pot in 1993, and ending at historic Cafe Wha?, two blocks south, where a reunited Van Halen played in January 2012. Cafe Wha? is owned by Manny Roth, David’s uncle. Whole thing takes about four minutes. You’ll love it.
