Evidently there is a yellow jacket nest under a bucket helping to support the trampoline by sitting on a leg. So, basically, when we jump, we shake the nest, so when Laura and I are jumping on it in the rain because, well, it's extra bouncy, I get stung twice. Ouch! Daddy is planning to lead an invasion of the nest as soon as he goes to Home Depot to get the stuff to attack them with. Go Daddy!
