To be filed in the good-but-not-exactly-clean fun files: Renee Seamount’s urban guerilla style of birthday fun will happen again this year.  The plan was originally to go to Spain to take part in the tomato flinging events that always take place on Aug. 22 (Seamount’s birthday). The budget wouldn’t go there, so for the past three years she’s assembled a motley group of individuals who meet up at the salon (Renee’s Chop Shop at Court A and Ninth Street) and trundle off to an undisclosed location to fling tomatoes at each other, or just watch.  Collect your tomatoes now (rotten ones smash onto opponents best) and plan to meet up at Seamount’s shop at 5 p.m.  Participants will receive a T-shirt and hosing-off with warm water. â€" Jessica Corey-Butler
