My DIY fire pit is in a roundup of DIY fire pits on BobVila.com! You can see them all here. As an update, the fire pit is still going strong. B just used it the other day, although he hasn't had much opportunity lately since we've been in the rainy season for two months. The only thing I'd do differently is maybe put some capstones on top of the open cinderblock holes, which I can do as soon as I remember that while I'm at Home Depot. Anyway, check it out!
