Had a really weird thing happen, but we're new to popup camping so maybe it's a thing we just don't know about. After we removed support rods from one slideout, we noticed a weird humming and suddenly DOZENS of flies began to pour out of the tubes, I smacked the rods on the ground and MORE poured out. There were a few in the other end's tubes as well. Anyone else run into this or have any explanations as to WHY this occurred? We were only there 4 nights.
