I swim at an LA Fitness here in Carmel a couple times per week. It's okay. The water is a little too warm but I usually have a lane all to myself the whole time. The main reason I joined is because I can go right after school instead of waiting for the 7:30 pm swim at Carmel High School or the YMCA.
Due to no gutters or backwash the pool gets really wavy if there are 3 or more swimming. I just figure that's good ow training.
