Big Hollow Herps

This is the first time I've seen a black rat snake this year and it was a big one.  I only got to look at it for a few seconds as I unitentially spooked it, but it was probably close to five feet long.
It may be that the big hollow prairies are becoming more comfortable for local reptiles as more brush is cleared and more sun is reaching the ground.

 
The snake was able to quickly disappear into the pile of rocks.

Garter snakes seem to be a nearly constant presence around big hollow as well.
