We have a large yard but it's basically a hill and it's too steep for a swing set, trampoline, or climbing dome. I really want to get the kids some fun outdoor toys. We have a small basketball hoop, some nerf guns, all different kinds of balls and wagons, a small baby pool, scooters. I REALLY want to get a small bounce house but DH has given that a big NO. My boys are almost 6, 3, and almost 2. What are your favorite/most used outdoor toys that don't take up a ton of space???
