Hi - I am looking for any ideas of what to do for a nature theme for a cub Scout day camp next week. Just found out tonight that I was put in charge of the nature station and so I am posting for ideas. We can do a nature hike and have a scavenger hunt, hike and point out types of trees, plants, shrubs, etc....not sure what else? Have a capture the "tree/flag" game in the woods? Any ideas would be greatly appreciated. Many thanks. -Victor
