I think Garter Snakes are camera shy because they know their colors just don't capture well. Herbert has distinctive red stripe where as Petunia is more yellow/orange. We moved the COLD FRAME for the summer and found Herbert sleeping beneath it. It took him (?) a few minutes to wake up and decide which way to go, so I had time to grab the camera (after a little scream of course). We see others around the yard, but these two stay around the garden.
Here is the link to a picture similar to PETUNIA.
Here is the link to the first year notes about PETUNIA and HERBERT.
