Erikaaaits pretty primitive - its good ole free camping in the woods - not at a campground or anything.
The basic notion is that were camping at the base of Hood (or wherever there isnt snow lol) and skiing there for the summer. I assume we can go into town to do laundry when needed (but its 45 min away) ... we will be staying in a tent but driving to the mtn each day
Sweet!! you'll have a great time. few things I've learned backpacking:
Pee rag - Bandana, tie it on your pack/ A tree so it gets sun and sterilizes in the sun. only use it to wipe pee, but it'll help with UTI's.
Metal trowel - If you plan on pooping in the woods, get a metal one. Plastic ones break. On the same note, the 3-rock method is the best way to wipe in the backcountry. Exactly what it sounds like.
LNT - Leave no trace. Should be obvious but don't leave trash or anything, and try to not leave food out, it's bad for the animals.
Pumps are better than gravity filters - Iodine is also an option if you don't have regular access to clean water, but I've always used MSR Pumps and they've worked great.
DON'T USE BUG SPRAY NEAR WATERPROOF THINGS LIKE TENTS AND JACKETS! - Seriously, it will basically melt the waterproofing even if it's just on your skin from hours ago. It's better to wear rain gear at all times (pants and jackets)
P-Cord and Rope - have quite a bit of both parachute cord and rope, they'll come in handy. Learn some knots too. I'm not sure about the bear situation on hood, but bears aren't worth messing with, learn to do a bear hang.
Extra Tarps- 2 or 3 to make a lean - to for cooking, one to "burrito" packs and whatnot in overnight, and one inside the tent. You could use one in and one out too if that's your thing.
Leatherman- incredibly useful to have pliers/screwdrivers/knives etc. I'm assuming you'll be close to your car so a toolbag in the car would be fine too.
That's what I've got off the top of my head, but I'm sure I'll think of more. Let me know if you have any questions!!!
