This post is the set up phase. It took an hour to set everything up the first day. I did it two days in a row and set up everything by myself. I purchased 4 sets of clubs, balls and a "bag" from Meijer during a clearance of summer items.
Hole 1: World Book sets and pool noodles.
Legos for the "holes".
Large picture books for tunnels.
Book ends for obstacles.
The book basket obstacles were a favorite.
I saw this obstacle at a Teen Putt Putt. Not suitable for preschoolers!
Hats as obstacles.
Pool noodles for water traps.
Scarves and hula hoops for sand traps.
My favorite: Hills using mats from our "tree house".
If your library does this program, please leave a link in the comments. I tried to use what I had to keep this program below budget.
