Last night I took an hour I didn't have to spare and went over to Kickapoo to see how carrying my new gear was going to work out. (Pretty well, it turns out -- I kludged up something to carry the weight of the 500mm lens on the tripod mount ring, and it works well, and I was able to handle both cameras without much trouble.)
In a backwater off the river along the trail that goes straight from what I think is called Number 6 Pond south to Rt. 150, I got a brief but clear look at an otter! As far as I can remember, I've never seen an otter in the wild before. Unfortunately, I messed up the switches on the camera, and I wasn't able to get a picture in the maybe as long as five seconds before the otter disappeared.
