A quarter sized spider appeared on the floor of the rec center bathroom. My first thought was it is possibly poisonous, smash it. But I was in a public place with people who might be brave enough to catch him. So I told the lifeguard, he radioed another person. Soon another lifeguard appeared from the bathroom with a cup with a piece of paper on top and heard the outside door open and close. I watched with an enormous grin, then began swimming for the day.
