Funny, I just had a similar experience with a wren's nest and also in Athens. (Athens, TEXAS).
Left my jetskis at the lakehouse (on trailer and covered) for 1 week. Hooked them up last weekend and brought them home 80 miles away. After I got home I noticed some leaves and grass protruding from the rear jet nozzle/transom area on one of the skis. A bird's nest with 4 eggs in it had survived the trip home at speeds of 70+ mph.
