I put this together on my own.  Had a couple problems with the thread of some of the screws, but overall it was pretty easy.  Don't be overwhelmed by all the pieces, ladies.  You can do it!  My son watched from the window as the assembly took place, but he had to come and try it out before I could even get all the way finished.  He was bursting with excitement!  I'm looking forward to having the whole neighborhood over to play!
