I want sod sooooo bad! I'm jealous of your yards!!! It's just not in the budget for us though. We were quoted at $10k for the backyard only (from 3 different places)...it'd be another $5k to do the front as well. We live on .3 acres, so it's not like it's a humongous yard, it's just DC expensive, blah.
I'm hoping that next summer we'll have money saved up for it.
