Dwayne going green?

This morning I was having conversation with Dwayne over breakfast and he was telling me about a rain water recycling unit we can purchase. He explained that it is a big container that holds rain water and has valves attached with shut-off switches to route water in the direction you want it to go. I know we have had one of those tacky bright blue water barrels before but it was hard to actually collect water in it, plus it was just plain tacky looking! He then tells me that we can have the water go straight to the new garden we are making this Spring. For an investment of $90 we can water our garden for free. This really got me to thinking and I know I don't say this often but Mr. Dwayne might actually have a very smart idea! I guess we are both slowly going in the direction of really trying to conserve resources as best we can. With the way things are going with the economy I guess we all have to do what we can to save money.

Does anyone have one of these rain water recycling barrels? If so, would you recommend it? What things are you doing to encourage green living?
