I also spend a lot of my weekend time working on things around the house. Last year my dad and I built a roof-top deck on my house. Unfortunately I didn't get everything finished until November, so I've been breaking it in this summer. I also finally managed to stop my basement from flooding every time it rains heavily.
I really enjoy travelling and the outdoors. I spent an entire summer in Europe and had a ton of fun on two week-long trips backpacking and canoeing. Unfortunately my grad school schedule has prevented me from doing much lately. I've spent most of my time off visiting friends and family and building my roof deck.
