The first couple of days there always make me feel like a beginning swimmer. It's entirely different to swim in a lake than in a pool. You can't put your feet down (60 feet of murky water below me!) and you're not pushing off the sides of a pool, fooling yourself into thinking what a great swimmer you are.
It's tiring! Fifteen minutes at the quarry is probably like a half hour in a pool. But it's beautiful and if I get there first thing, no one's arrived yet and it's peaceful. One time, it started to rain when I was in the middle of the quarry. Level with the water, I was surrounded by the pings of millions of raindrops all around me. I didn't want to leave when the lifeguard blew his whistle!
The best part of the quarry is that it's just 5 minutes from my house, instead of 15 minutes to the gym. So easy to get 30 minutes of laps in. I've lost a lot of my fear of gaining back my weight because of the quarry. If I gain a pound or two over the winter, I know I'll work it off in the summer because I swim almost every day. The only downside is having to wash my hair every day. It would be so much easier to be a runner! But boring, no?!
P.S. That's not me jumping off the high dive!
