Here in Iowa we have cold weather moving in(finally) Winter hasn't arrived and my wild population is still active. My kids told me they saw a big female out front in one of the shelter areas. After a few days of mid 30's we are suppose to return to low 50's during the day. I'm sure my wild one know how to deal with this crazy weather but I'll do a yard sweep checking for any caught out in the cold. Found a big female in that situation a few years back. I think she was awaiting death in those temps. I took here in and we enjoyed her for 2.5 years more. She was a great snake.
