There's no Lowe's event this weekend, but there is a free Home Depot kids workshop tomorrow. It's available to kids 5-12, runs from 9am-noon, and they'll be making a periscope.
Ahhh, that brings me back. As a kid, I was obsessed with becoming a spy and begged my family to buy me every stupid spy toys available. The only problem was that upon getting them, I learned (A) there was nobody to spy on in my neighborhood and (B) I didn't need any of the concealed weapons as squads of assassins surprisingly weren't hunting me down.
