Gates open at 6:30 p.m. tonight for Darien’s annual fireworks display at Darien High School. Expect the viewer area to be farther from the rockets’ red glare this year, but you’ll still see the bombs bursting in air. The stadium seating available most years is off limits tonight, with a construction project involving underground power lines making that area unavailable. There is an area on the far side of the school for those who want a little less bang (see the fuzzy map below, upper righthand corner). If you want to park your car on the high school campus, you’d better have a parking pass with you.
