Play was the best and I had both worlds, inner city St. Louis and rural Mississippi.
In the city we climbed fences, played in vacant lots, explored open trash pits found all sorts of good stuff for our imagination, had battles with dust filled paper bags, played 'Knights' with trash can shields and broom handle swords, had play weddings with the rice we scooped up from the sidewalk by the big Catholic church on the block, rode sleds down a hill in the convent grounds.
In the South was adjoining family farms where we could play in the woods and pastures, go skinny dipping in the streams and ponds, swing on rattan 'monkey vines,' kiss second cousins in haylofts. Big dinners with tasty fried food - especially church homecomings where everyone brot a covered dish.
The worst? IDK. All I can remember are the good times. Being sick was no fun and getting my butt beat was a negative, but no real bad times.
