Out of ideas for your child's next birthday party?  Look no further and bid on this item.  Hart's Gymnastic Center has donated a birthday party package.  This package includes 60 minutes of gym time and 30 minutes of party room time.  The party is good for up to 10 guests (including the birthday child).  Additional guests are only $5 each.  The best part of the package is that they clean up the mess while you have all the fun!  Also included with this birthday party is a helium tank donated by Party City in Kent.
