Ciss – I also saw what looked like raccoon prints mixed in with the otters.
Brad – These were "gimmies." The tracks you didn't see were all the mosquitoes swarming around my face. Next time I'll bring better netting and stronger repellent.
Dr. Tom – Excellent points. The wet season's trash (i.e., extra water flushed to tide) is dry season's gold. We need to do better.
