Mrs. Frizzle taught us kids learn best by experiencing things first hand. Though despite constantly checking Craigslist, you haven't found any magic school buses for sale -- so today's deal might be your best educational option: Half off tickets to the 18th Century Market Fair at Claude Moore Colonial Farm at Turkey Run on July 16 and 17 or October 15 and 16. Pay $3 for two children's tickets, $6 for two adult tickets, or $9 for two adults' and two children's tickets (a $6, $12, and $18 value, respectively). Hosted on a working farm, this fair gives a glimpse into the history of our nation. Kids will love bobbing for apples; seeing chickens, turkeys, pigs, and cows; and testing their quill writing. And with plenty of period food available to munch on, you can practically taste the history.
