Here is a thread for the worst pools that you competed at.
Mine is University Of Pittsburgh. That is the worst pool ever. I don't know if it was the pool or the situation at the time but I am swam very crappy at that pool.
Walls: Hillendale in Silver Spring MD circa 1990. An outdoor 25m pool, MCSL summer league. The walls were slipperier than glass - if your flip turn wasn't perfectly square on, your feet would slip sideways and you'd get no pushoff. Backstroke starts were problematic as well.
Blocks: Iona College circa 1993. They had pretty nice blocks... that were barely attached to the floor. The blocks rocked back several inches on every start.
