5-6 ft sounds managable...what about thickness? Are we talking as thick as an adult ball or slimmer? Every video I see of retics they are constantly darting around, I assume this would be true for the SDs as well, do they every calm down or is this always going to be an active snake? I have a 5 year old son and I don't want to bring any snake into the house the he wouldn't be able to handle (with constant supervision of course)
