So Ive handled snakes for a while, but 4 months ago I acquired my first snake.
His name is Miko (in my picture), and he's approximately a year and a half old.

So... 2 questions.
First off, I keep his tank at 60% humidity always. So i know its fine.. But how long is he okay to be out? I live in New Mexico and there's almost no natural humidity. And he loooves being out. I just want to know how long he's okay in the dry air.

Secondly, tips on getting him less shy?
I got him from a lady who had waaay too many snakes. He eats amazing. Thankfully, but i got him almost completely unhandled, at a year and a half old. I got bitten several time in the first month, as he was freaked about being touched. But he's calmed way down since. (I also started with like 10 minutes 2 or 3 times a week.. and now he's out every day minus right after eating for 48 ish hours )he likes to be out and likes to sit on my neck or in my pocket while I do stuff... but touching wise, he's verrry jumpy still. Whats the best way to help him out of that?
