Thank Vets today (any day really) for their service. Also take the time to explain to your kids/friends kids what the holiday is about. Unfortunately a lot of people take their service for granted. Make sure your kids aren't among that group.
I was a kid during the Vietnam War when it was in vogue to spit on Vets, and call them "baby killers". My Dad would have no part in that, and taught us to respect Vets because they protected us, and kept us free. The "baby killers" were the politicians; Vets were doing their duty.
