What he said!!!The number one survival tool for anyone packs easily and weighs nothing - It's a good attitude.
You really don’t need to carry an entire ambulance in your camelback. I carry more tools to fix my bike than I do to fix people. I was a certified EMT in California & New Mexico and trained in Wilderness SAR, confined space & high angel rescue in the mid-nineties. You can do a lot with a little when it comes to a majority of bike related accidents. When it comes to severe internal or head trauma though, unless you can get someone to an OR you’re not going to be able to do much.
A femur fx can be pretty severe if the patient goes into shock, and in most cases without a traction splint or morphine you’re not going to be able to do much to relieve the pain. Unless the patient passes out, they’re going to be difficult to transport over land.
I carry some pain meds, a triangle sling, a Sam splint, a wire splint, tape, and the typical bandages, swabs, etc… With a Sam or wire splint and a couple of jersey arms or your tow strap you can make a splint for about any bone. Duct tape is universal too.
Space blankets are great if you’ve got someone going into shock.
A couple of lighters are a must as well – I carry one in my tool belt and another in my camelback. There’s no excuse for freezing your ass off if you have fuel for a fire (i.e. your buddies’ bike – chances are he won’t be riding it out…)
Another thought when it comes to the “psychology of survival” – attitude has more to do with survival than physical conditioning or environmental factors. There are plenty of case studies, specifically for parties lost at sea, where those who are seemingly physically fit die and someone else, who by all logic should have perished, survived. Same thing goes with children. Children who are too young to be scared, and who essentially just find somewhere to cozy up and take a nap do much better than older children who have a tendency to freak out.
Survivors don’t wonder around in a panic in the middle of the night, they light a fire and shoot the shit with their buddies around the campfire…
Fire source, a half dozen or so energy bars, some idolization tabs if you like, a map of the area and a compass / signaling mirror, emergency bag (better than a space blanket because you can crawl inside), extra medication if you take any, a basic first aid kit and a index card with all your vital info (emergency contacts, allergies, blood types, pre-existing medical conditions). A cell phone (if you have coverage) or SPOT if you don't can save you a few cold nights...
I think bike failure is more likely than anything. A busted chain can ruin your whole day and a chain braker & master links are light.
I usually only ride solo in OHV parks (where someone will find me eventually), but if I'm going 'off the map' I often carry a 40 S&W DAO semi-auto.
EDIT: Oh yeah, I also carry about 25' of 1" tubular webbing (the kind rock climbers use) for towing bikes or a hundred other uses. You can use it to secure a splint, help build a lean-to, tie up a meth head, hang game, or (if you add a couple of well-placed carabiners) you can use a mechanical advantage for extracting a bike...
Definitely +1 on the space blanket. My last one kind of fell apart and I need to get a new one.
Riding out injured is the number 1 reason that I want an electric start bike.
Carrying enough stuff is always an issue in a dirt bike. I always carry a backpack and I carry way more than just about anyone that I have ever been on a trail with. I'm lucky if the people I ride with bring enough water to not cut the ride short. I try to always have a first aid kit of some kind. Nothing too major but some stuff for bleeding and a way to wrap it up.
OK, so I tried this tactic on my wife yesterday.....I even said when we're financially capable...it'd be a good idea if I "had this option". Didn't go overas well as expected.....
