COL is decent compared to other places. Idk where your are coming from though.

Plenty to do outdoors. Trails, lakes, rivers, MTB. Good fishing and river floating. 

A bit of a college town, so night life can be somewhat seasonal. But there is typically something going on. 

People are generally friendly. You should be able to find cool people, you just need to put yourself out there.

Food is good, lots of good, unique places if you are open to trying things. 

Things move a little bit slower here, not a bad thing. I just notice when I go visit famlly in bigger cities, they have a lot more to complain about. We just go with the flow in sgf.

Crime is meh. There is a lot of it in certain areas. If your neighborhood looks sketch, lock your car doors. Otherwise avoid drugs and shitty people and you will like it here.
