Hi there. I have come across the requirements for a geocaching try-it and
badge. It was put together as a bronze award and is offered out of NY. I have a Junior and a Brownie myself and ordered one for each of them. They more than earned it just from being involved with this activity.

The cost is 95 cents each plus tax and was shipped out within a day
for me. Enjoy!
