You've spent the day assembling a playstructure for your children.
I got a little sunburned behind the ears. We got it from another family whose children had outgrown it. It's always nice when people are willing to pass on things that are still in good condition.
The instructions say that it should take 1 hour to put together. It took me and my Dad over 5 hours, including a two hour trip to Home Depot to get new screws. (Don't ask, there was much debate.) But we finally got it all together.
The boys absolutely love it. And that makes it all worthwhile.
