Now, I would like to say Boomer is a slow learner and that I was too optimistic thinking he had all the fun possible already and would appreciate the cover over the springs. But, maybe I am as slow as he is?
This is what we found tonight after it got suspiciously quiet outside:
Boomer tried to look dignified as we got the camera, laughing unmercifully. We got him out and he went off to bed in his crate.
Everything gets cleaned up tomorrow. Unless it rains.
