The Boy Scouts of America merit badge book about Geocaching. A resource for the sport of geocaching. This book is very much oriented to using geocaching by the Boy Scouts.
Definitely not my favorite topic, but I lived through it. I am not a Boy Scout, so some of the ideas referred to were new to me. My mom used to be an active geocacher so I knew the basics, but it was good to get some more info on the subject.
A good introduction of geocaching and the use of a GPS in outdoor sports. This book also covers etiquette and uses the principles of Leave no Trace. I read the book in order to get prepared to present a class to ten boy scouts. (27 Apr 13)
Read it again today to get ready to teach this badge again. I had 21 students in my class today and just finished getting two others through this badge last week. (25 April 15)
