Yes, I've gone back to the pool, with several more times planned for this week.
The fins I bought were way too long. I bought them at the third place I went to and by that time, I was giving up hope. At the pool yesterday, I spoke to an elderly gentleman who was wearing much smaller fins and he told me where to go to buy them. I had to travel to the far reaches of the city to get them--I'm hoping they work out better.
Here's what I like about the pool: people look real. So many people avoid going to the gym because they don't look like ads for Lululemon. You know what I mean: lean, mean biking/yoga/fitness machines without an ounce of untoward fat on them. Fortunately, these are not the people at the municipal pool. They're all ages, with a significant number of older people. I go around noon; most people with regular day jobs can't get to the pool at lunch so I'm not seeing the gym warriors. They're probably at their fitness clubs at 5:30 p.m. after work. More power to them, but I like the floppy, sometimes flabby, real people at the pool.
