Summer: Our sand box was huge, approximately 20' x 4', and my brother and I spent a lot of time playing in that. We had a wide variety of small tractor and implement toys. We had 2 uncles who were farmers, and my brother and I would each pick an uncle and pretend to be them, having our own farms and areas divided for fields in the sand. We spent many days farming in that sand.
Winter: Hot Wheels was a great winter pastime. Already having a large set of our own, we also inherited a large set from older cousins. Tons of track, 2 power boosters, many loops, banked turns and curves, and a lot of worn out cars would provide weeks of fun when we were tired of sledding. I remember the purple plastic track connectors would get worn out and cracked, so we were constantly making replacements out of cereal box cardboard and tape.
Good times. Good memories.
