It's Labor Day Weekend. #1 son is off to college. HTP and I are on our own. For the last couple of nights we've heard huge explosions in the night. Last night I actually called my folks across the lake to make sure that they were OK. It sounded like someone's propane tank blew up. Tonight my folks called me to find out if I was OK. I don't have a clue where these explosions are coming from. They aren't your typical firework explosions. They are "rock your house" explosions. When I hear them I wait and expect to hear sirens but none follow. Huh? All I can think is that we've got weekenders with heavy duty explosives this weekend. Fun, right? Not.
