Last year we had the flagstone patio put in and although I didn't really love spending all that $$, I'm so thrilled that we went ahead and splurged. It's so much nicer being in the back yard now.
Once the patio went in last year, it seemed like we were constantly traveling and getting to the actual landscaping part of the back yard got put on the back burner. That, and it got to like 115 degrees and seemed to stay that way.
I've also got a bunch of hummingbird feeders in the backyard. I love watching the hummingbirds zoom around. We've got one that is almost all shiny green, one that has a ruby throat, and this little one.
