Scavenger Hunt Ideas

I have been looking for scavenger hunt ideas ever since I had
my first child and just recently I came across this one:

This is a traditional scavenger hunt where you get a list of
things to recover, that you have to bring back within a
certain time limit. Use common items for younger children like:
a ball, a coin, a leaf from a certain tree type etc. Now you
have to make up some rules, i.e. non of the items can be bought
or non of the contestants can go home and get any of the items.
You can be as creative as you want with this scavenger hunt.

Have fun!
