We spent the day at North Clackamas Aquatic Park today in Milwaukie, Oregon! It is a large indoor water park (what pool isn't indoors in Oregon???) with a wave pool, water slides, kids pool etc. You can check out the pool at http://www.co.clackamas.or.us/ncprd/aquatic/.
The kids had a great time and little Miss Sarah kept me going for 3 hours straight swimming from pool to pool. She has absolutely NO FEAR of water at all and wanted to be in the deep end of the pool when the waves were going, and loved going through the waterfalls, etc. My idea of renting a house boat on a lake for vacation is going to have to wait, I can just see her in the water every opportunity that presented itself.
