Krista,

Kudos to you for thinking this through and subjecting your plans and preps to this group. I enjoy the periodic mental exercise of these scenarios. But the more I think of them, the more skeptical I become for my own situation because only an armageddon/TEOTWAWKI would require me to have no option other than walking hundreds of miles. If things get that bad, 90% of us are toast -- violence, starvation, disease, heart attacks... we'd be dropping like flies.

Nevertheless, it comforts me to know that I can buy myself and my dog and some friends, perhaps, a few days if things were ever so dire.

In my Mad Max scenario, I'd have my bikes on my SUV (I have a hitch-rack) and bike trailer and a trailer-stroller on top (I have a Yakima Loadwarrior roof basket), and a couple pair of hiking boots in my vehicle. In fact, I always have a pair of hiking boots in my SUV....

If you're serious about this (obviously you are) then I echo the recommendations of others in this thread to get a bike - and a bike trailer/stroller. The trailer in this photo below is rated to hold 100 pounds (Croozer Dog Trailer). I have another version of this trailer that can also function as a stroller and has a luggage rack. Your child and dog could ride in it when they tired. Put a tarp over it and you could keep your things dry.

You can often find on Craigslist used bike trailers for carrying children. That trailer could also carry gear and/or your pup.

My dog pulls this bike (bikejoring) but I cropped her out of the photo. On the day this photo was taken I not only rode my bike but spent a lot of time walking it - very easy to walk this bike-trailer combo holding the handlebar with one hand and my dog leashed to the bike. You can ride and walk with your backpack or lash it to the top of the trailer. That bag on the back of the bike also carries a fair amount and has two panniers that unfold when the sides are unzipped. You could also put panniers up front. I have this mountain bike for the purpose of bikejoring.

For a bug out scenario you might want a "hybrid" bike with smoother tires. Any bike would be a heck of a lot better than walking. Even if you got just 100 miles out of it, that's better than starting out on foot.

Water weighs 8 pounds per gallon. Really would be nice to have the option of putting that in a trailer-stroller.

I have some other gear suggestions I'll list in a subsequent post.
