Howdy,
Gerry led me here after giving me two of his hatchling infernalis. I'm in Woodside, CA. I've worked with Santa Cruz (aquatic) garters (fairly easy) and Coast (terrestrial) garters - very easy; we have a nice red morph up here and they'll eat anything that moves (including each other if you're not careful).
So far the 10 day old red-sided's aren't eating; coast garters would be by now but I'm hopeful they'll come around by next week.
Oh and I also have an Oregan red spotted garter that's very attractive and feeding voraciously on mice.
