We spent out weekend on something we've wanted to do for a few years: the overnight program called the Lexington Liveaboard. This is an overnighter that the USS Lexington, a WWII-era aircraft carrier docked in Corpus Christi bay and converted to a museum, conducts with scouts and JROTC programs where the kids (and parents for our kids' ages) stay overnight on the ship with a full schedule of educational (and fun) programs with the staff there. When we visited the USS Lexington a few years ago (the kids were so little!), we were really jealous of the families doing this, and were determined to take advantage of the opportunity if we got a chance. Our cub scout pack goes every two years, so we signed the whole family up.
The quarters were cramped! I should have taken a picture of our accommodations metal bunks stacked three high. The women were on one end of the ship and the men were on the other, making me wonder why I bothered to come... but we had a good time. The boys loved running around and exploring, we all got plenty of stair/ladder workout, and Zack was promoted from wolf rank to bear rank. We didn't get much sleep but we did have fun!
