Balloons for the mailbox (people still got lost)- $9.00
Finding shovels in the off-season- $13.50
550 lbs. (quite literally) sandbox sand- $60
Cleaning up after a vomiting child at 2 a.m because of a sugar and 'dirt cake' overdose- priceless.
p.s.- I grant permission to anyone who wants to copy this fun idea. Just don't overdo it on the sugar...
