CAP Inquiry: How much commitment

I saw a post on rec.aviation.piloting regarding CAP.

I'm wondering if any of you wouldn't mind answering an inquiry regarding CAP.
I would like a bit more info, if that's possible.

I'm located in Maryland, and am going to look into joining.

I'm curious as to what type of commitment is typically required.
I'm looking for 4th seat type of volunteering and moving up over time.
I will be getting my Private ticket next summer.
(I had to delay in the middle due to some family medical issues).
For example, meetings every week?
What about weekends? How often and for how long?
What if you have vacations and kid's/family issues occasionally?

I wouldn't want to be a "minimum time" person, as it isn't as valuable to the CAP.
I'd like to volunteer honorably and insure that I could make more than a minimum commitment
before I join. I'd hate to use up valuable training time just to have to quite after a few months.

Any of your thoughts would be appreciated.
