Shut down the street, light up the barbecue, turn up the amps. Say, “catch ya next year” to summer and help raise money for the Arcata-Camoapa Sister City Project at the 35th annual I Block Party, taking place Monday, Sept. 5, from noon to 6 p.m.  in front of Los Bagels in Arcata (free). This hometown favorite street party has everything: mouthwatering barbecue, live music from the Jim Lahman Band, the Latin Peppers and Absynth Quartet, local microbrews and desserts and a raffle and silent auction. Fun for the whole family.
