We also got a great deal on a little 8' trampoline for the kids a few weeks ago, only to be given a 12' trampoline for free this weekend! Lesson here? Patience. :) Haha. The kids tried out the "big" one with water balloons today and we could hardly get them off again to come in for supper (a very late one) and bedtime! It also ended in an all out family brawl when Daddy hit Mommy in the ear with one of the water balloons and she jumped onto the trampoline to tackle him.
