Kenyan Sand Boa activity level?
 

I'm hearing a lot of "oh you'll just about never see him", but also "usually under the substrate", and even "out in the open a lot". There doesn't seem to be a solid answer so I guess I'll ask here.

How often does one see their KSB out in the tank? Is like you'll only see them at a certain time of day? Will I see it out and exploring every few days? Or will I catch a glimpse of him once a week?

I know these boards aren't very active in these parts so any answers are appreciated! Thank you!
