Batter up! The Crabgrass Band is tuning up and the Humboldt Crabs are getting ready to take the first swings of the summer at Arcata Ball Park tonight at 7 p.m. There are no tickets for sale at the gate, so make sure to get your tickets online at humboldtcrabs.com before you take yourself out to the ballpark ($10). Gates open an hour ahead of start time so you can get your hot dogs, drinks and seats, and get your glove on to catch a fly ball.
