I started the day at the airport flying Young Eagles - I flew 3, pretty much the same route every time.
Back at home, we replaced the expansion tank on the water heater. Apparently those things only last 5 or so years, which I was unaware of. The interesting thing is I've (now) figured out that it failed ages ago, it's just when it started to rust through that I realised it needed replacing. Now I can tell when the pressure over flow starts running from time to time that it's time to start shopping for a new one.
