We bought a soccer goal/rebounder at a thrift store for $5.99. Luckily, we had the station wagon with us! You have no idea what we've strapped to the top in the years we've had this car.
It was a real hit with Andrew! I can forget about my colonial style kitchen garden, because our narrow back yard is now a sport court. Of course, I've found my own uses for the new toy. It's ideal for airing a king-size down comforter!
