The turtle is back.
I've lived in this house for about 23 years, and just about every May we see a turtle that comes to lay her eggs here in one of my gardens. This results in extra pool duty in mid August, to rescue the babies who fall/crawl into our pool. With vigilence, most can be saved.
I had been in and out of the fenced in area around the pool, so she must have gotten in when I was upstairs. She scared the heck out of poor Niles (my Chihauhau).
