Wow! I just stopped by a precast place today in Mesa called Stimco Precast. They have some awesome concrete planters. I got some that had this real cool stain that made the piece look like leather.
It looks like they are in the middle of upgrading their display area so I'm planning to check it out again in another month or so. Cool stuff.
It was at 1054 S. Center Street in Mesa. I found them on the web while I was searching for patio planters. Their website is www.stimco.com.
