Recently purchased a -15. Reviewing the logs revealed a delightful surprise, but first some background.
The glider was last flown in 1998, then was sold and inspected in June 2004. It flew until September 2004 when the new owner found that the right wing would drop from level flight. Upon inspection, the following was put into the logbook:
"Cut 5 holes in the bottom of the right wing and removed 12 lbs of grain and 4 dead mice. Repaired the holes and primed. See Form 337 for details."
Amazingly clever little beasties...
