Starfish Food

I have been thinking about how much water we use in our yard. The kids have their little pool, we run a sprinkler for the lawn, we water the flowers and plants, etc. It all adds up after a while. I would like to save money and water. I have been looking for rain barrel workshops in my area. I would like to learn the right way to collect and store rain. I have started looking online to see what is offered around here. Once I find something, I will sign up and then once I know what to do, I will order a barrel.
