Hello I am the leader of a scouting group for girls ages 9-16.  We are planning on taking a 3 day/ 2 night backpacking trip at St. Croix State Park the second week of October.  There will be from 9-12 girls, 2-4 adults.  My first question is: is there any help I can get with planning this?  Every time I look at checklists I get so overwhelmed trying to figure out how to mold it to our group.  How many tents? What degree sleeping bags? What size backpacks? etc.... My next question is: does REI rent gear out?

Thank you for any help
