I don't know about you, but our family spends a lot of time outside. Especially in the summer, but during the entire year really. We have been fixing up the back yard lately (as you know we installed a volleyball net among other things), so what we need now is some nice outdoor furniture. I personally love Adirondack chairs; they have to be the most comfortable outdoor seat ever! The sloped back are so comfortable! I especially love Adirondack rockers; they combine the best of 2 worlds! A couple of these on our back patio or placed near our volleyball court would be great. Especially for family members who can't play, but still want to enjoy the fun!
We have also been discussing building a pavilion, and putting a picnic table underneath. It would be perfect for all our family picnics, or for when we have company over! The kids really love eating outdoors, so this is on our accomplish-ASAP list.
One final piece of equipment we are looking to put in the back yard is a playground. Even if it's just a couple swings and a slide, the kids would love having this right out the back door!
