Talk about satisfying. It's a little unbalanced as far as exercise goes, though. Hopefully I won't end up with just one big, beefy arm.
Also, for the MIT people in the house, today I found practical application for my Course 19 education when I went slithering around my house's crawlspace to check out the heating duct that's messed up. Who knew practice negotiating insulated pipes without getting fiberglassed would ever come in handy.
