Who determines these swim waves?

I have one thing to complain about. Swim wave times at Hyvee this weekend. Female under 29: 6:48 am. Transition closes at 5:45. What am I suppose to do for an hour? I have thought of several things. Take a nap, go out for breakfast, hang out in the beer garden. But the one I have chosen is to time my warm up to end exactly at 5:45, put my shoes in transition, get out of transition, stretch. By the time I am done doing that, the first people will be out of the water. This is a unique opportunity because now I can watch how the elite group do their transitions and maybe pick up a few things that could help me out. Normally I would be swimming still so you never get to see these guys/girls. Since these will be the people winning my age group, it couldn't hurt to learn from them. Also by the time my wave goes off, some people might be finishing. lol. Just kidding. Almost will get to see them come back in from the bike to run. So by the time I am done, all the food will be gone and I will have to wait 2 hours for a massage. Hmmm...that sucks. Oh well, what can ya do? I am heading out to the lake tonight for a swim. I was debating about whether or not I needed to get in the water without my wetsuit. I am pretty sure I will be fine, but it can't hurt to get out there and swim just to make sure so I won't have that tiny bit of doubt. And when else are you going to get out and be able to swim an hour with a life guard in open water? Not very often. This will be nice. Last couple days' workouts: Monday: 30 min swim because the pool water was 96 degrees. Hot tub water: 101 degress. Hmmm...little warm don't ya think. I about passed out so I decided it was time to get out. Tuesday: 45 min run in am. It was hot! Wednesday: 30 min bike this morning and an hour swim tonight. Thursday: 30 min run am and 2 hour bike after work. Friday: off. Picking up my packet, going to Rob's softball game and then to the Icubs. That is the plan anyway. Rain could alter these. Saturday: 45 bike and 30 min run. Equipment check and gather it up. Clean up bike and take to bike check in. Try to get to bed early(ish). Probably getting up at 3:30 Sunday. Going to braid my hair which will take the most time. Also wanting to get to the race sight so I get a good parking spot. the DSMtri club has special closer parking. So I want to get there probably around 4:45-5 just to make sure I get a spot there.
