Thanks for the info, Hikermor and AKSAR. I'll look into it -- I was thinking of taking some SAR courses that'd certify me for my state, actually. (Not that certification necessarily means much. I am guessing legal liability is one of the motivations behind the certification.)

The main problem is work -- in addition to the pressures of the job itself, I really have to be there for certain tasks. But if it's Sunday and Monday, I just might be able to make a schedule in such a way as to give myself the most flexibility on those two days.
