Two Guys and a Truck present Friday Night Live, a free outdoor concert series for the summer in Old Town Herndon.  This is the place to be on Friday nights in the quaint town of Herndon. Buy drinks (sodas, waters and beer) as well as ice cream and pizza slices and chill out on the grass and people-watch. This month, hear bands such as Hyjinx on July 4 (catch fireworks and the band plays 'till 11 p.m.); Kristen & the Noise, a Dewey Beach party band; Jah Works (obviously a Reggae band); and B2B, the Jimmy Buffett tribute band. All this while you sit on The Green sipping your beer.  Concerts are from 6:30 to 10:30 p.m. Go to www.herndonrocks.com for more details.
