You wouldn’t normally think rain would help anoutdoor event, but in the case of the 18th annualSpring Swine on the Vine, it may havedone just that. About halfway into the CapitalClub’s beer and barbecue event on April 27,raindrops drove partyers into the tent where LoveSeed Mamma Jump entertained with covers ofwell-known rock songs long into the night.
