Although We have 3 kids (15, 16 and 18), I'm kind of in the same boat.
We used to live in a community where little kids, including mine, would run around having a blast trick or treating.
For 7 years now, we've lived in the country where there really isn't anything going on, so we'd go to the old neighborhood and let the kids do their thing.
Last year, my son and a few of his friends would hide in bushes, around cars etc. and pounce on bigger kids that would try and steal candy from the little ones.
(he's a good boy)!
This year we went to "The Villages" listened to a live band, ate, then came home and watched mission impossible 3. It was fun, but I sure do miss the little ones running around in their costumes!
I'm looking foreward to grandkids in years to come!!!
