I've read conflicting things about what to do with your squirrel after shooting it.
Shoot it, field dress it, then put it on ice right away
Shoot it, field dress it, then put it in a bag
Shoot it, don't do anything to it, put it in a bag, and wait to clean it until at home or by vehicle

What do you do to keep all the meat from spoiling while reaching your daily limit? The place I'll be going is about 15 min from home.
