I was exploring sl, and came across this sim, a scout camp. And fairly realistic in that there were bees, a bear, tents... It reminded me of a scout camp I visited often when I was a teenager (I knew the manager and was friend with her daughter), You can hike, ride a horse, swim, boat, and do a lot of other activities at Camp Kawabata. There was a bonus for someone like me: a weather station in the tower! Avatars aged 5-18 are welcome to join the scouts.
The sim is rated PG
