Geocaching

 Geocaching is to divide into 2 different groups to find treasure with GPS in Pigeon Mountain. We went to Pigeon Mountain on Monday and we walked. The teacher divided us into 2 groups. My group was me and Donghae 3 man students. Inside of GPS there is compass system and meter ststem so we used these system to find the treasure. We found 3 treasure. It was difficult to find treasures in the rain and the Pegion Mountain was too huge, so it was hard to find and my legs were hurt. I was so hard and I was unusual experience to me because I used GPS for the first time.
