Backyard obstacle course on a budget

Built one this past weekend with stuff we already had:

• Pool noodles duct taped between trees for crawling
• Hula hoops laid out for jumping
• Old ladder for climbing
• Cones for weaving
• Balance beam made from a 2x4 and some blocks

Kids (7, 10, 11) are OBSESSED. Literally set up a "competition" and keep trying to beat their times. Cost me like $15 for the cones. Way better than sitting inside.
