I have a fairly well-organised mind (unlike the rest of me), and I always pencil-in June 1st as the date on which the pool is opened. This year, however, I've broken with strict tradition, thrown caution to the winds, and opened-up a week earlier (oh what it is to live so dangerously).
Anyway, all went well. The pump started up OK. There were no dead badgers at the bottom when it was uncovered. And the water has returned to its normal crystal clarity after just one day. I'm now waiting for the water temperature to rise a bit, then it's FUNSVILLE.
