I've had enough weather!

Forget a building a house...we're using that foundation for something more practical. I just can't decide what...which do you vote for?
Skating rink/extreme snowboarding course?

Or lakefront swimming pool

?

Too bad I wasn't home during daylight the day before when all of that green grass was under water.

I'm kinda leaning towards the swimming pool, problem is, I just can't figure out where I'd like the diving board.
