There's also a cool video about collecting rainwater from your gutters, etc. to water your lawn with. This requires a bit of work upfront but could be very useful and resourceful. Here in Indiana in the spring, we get a ton of rainwater, so it would be pretty plentiful.
Another helpful tip that I have acquired is to lower the temperature on your water heater down to 120 degrees from 145 (if not already turned down). 145 is pretty standard so there's a good chance that that's where its at right now.
I found some pretty sweet deals on flights if your looking for a weekend getaway from Indianapolis or other midwest cities. You can also plug in your current city and find other specials as well. No financial interest for me, just sharing: http://travel.southwest.com/specialoffers/topOffers.html
I'm almost 30 years old, living in the midwest, but love to travel around the world when I can. I have a great girlfriend, group of friends, and life in general. I seek a simpler existence in a challenging way every day. I like to learn all the time as well. Life is all about the people and places you meet.
