The swimming pool - Summer 2008. We decided to put in an underground playroom. Two Christmas' ago it was the trampoline. The kids loved it and it wore them out so everyone was ready for bed. Now it's swimming! It works as a reward system also. If you clean your room -you can swim! We began on May 19th and started filling on June 19th, Lauren's bday. The kids loved watching it fill up and couldn't wait to get in - so they did. We decided to put a salt generator in to cut down on Chlorine because the girls blond hair turns green. It has been maintenance free for the most part. The first evening Keith and I decided to use the heater for the hot tub a fire started in the heater - it was replaced and now all is well. Yes we needed the heater because the prevailing southwest wind (there were white caps in the pool) makes you cold.
