Hi H.,
We are in a relatively small town, and have a community pool.
The minimum age for children to attend alone is 11, however it's only open daylight hours and is heavily chaperoned by adults that either work or volunteer there.
Personally, I have only this year allowed my 13 year old to attend evening/night events such as sports or practices without a parent. I make sure she has a little emergency cash hidden in her shoe for instance, and a fully charged cell phone. I know from experience that these events are not only attended by adults/families I know, but are also patrolled by the local police.
She wants to be dropped off at the mall with just a friend or two, but even though some of her friends are allowed to do this, I still feel 13 is too young to be that far away from home alone without a parent/adult.
It is my opinion that 10 is way to young to attend anything alone. I would allow it if a small group of children were to attend with one of the kids parents in attendance as well.
It would also depend on the maturity/personality of the child. While I allow my 13 year old to attend some of these events without direct adult supervision, her and I both are aware that any adults that happen to be there are not there for HER supervision, but she is mature enough to stay away from "trouble" and/or immediately seek help should it be needed. She does not cave easily to peer pressure, has good judgment, and is comfortable with who she is.
My 8 year old.....even when she is 13, I don't think she would have the same level of maturity. It is the 8 year old's nature to seek "adventure" rather than avoid it. Ha!
I have attended some of these events and observed children that I know from being friends with my own kids.
Some of these children should not be without direct supervision, simply because of their personalities away from adults. We all know the kids I'm referring to. Personally, some adults shouldn't be without adult supervision. :-)
Stick to what you are comfortable with, and what you know your children can handle. What they complain about now, they will thank you for at 30.
