LOL.....so here's the trick....
You put them on the stage, put a dark bucket over them for a little bit to settle them down.
Then take the bucket off and snap a couple pics REALLY REALLY quick! LOL
Litterly I snapped about 6 shots, and then he took off like grease lightning...LOL One reason I don't post a lot of colubrid pics, most just want to run around....so those are the ones I tend to play with a lot, while actually taking pictures of stuff usually centers around boas and pythons. LOL
Anyway...sorry for the ramble, glad you liked the shots!
