Saturday is Free Comic Book Day! Find a store and take your kids, start them on a life of reading & adventure. http://www.freecomicbookday.com/
I know I was lucky enough to have a mom who drove me and my brother to comic stores and gave us a dollar at the local gas station to get a comic. We learned to read with comics. We learned about myth and fiction. We learned about art.
And we learned to dream.
Be that person for someone else and not spend a dime doing it. Go to an event this Saturday with your kid. Or go by yourself and see what awaits.
