I think you will have a great time. When I was a senior in high school, I took off for a 2 nighter with some buddies. I lived in Everett, so we headed to Mt Baker NF. We had way too much clothes (and the wrong type), low tech equipment, etc. We ended up getting lost and using a day to dry out. I had a lot of fun and learned a lot.

Make sure to take lots of pics and tell us about it.
