I think the entire bug out 'thing' is more fantasy than reality regardless of vehicle. Being out on the road just makes you a target. If one's location is that tenuous then they should have already re-located to a safer area from whatever they envision occurring. The TW, or any motorcycle or scooter, to me is just another tool in the tool box. Its cheap transportation for running errands and short trips should fuel costs become outrageous, which I think they will. In the meantime its just fun riding it, and having a bit of fun is a good thing!
You're right, it's mostly a fantasy. But for some of us, it makes us a bit uneasy about our situation.
I live in an apartment; in what is a decidedly urban zone. In the mountains; it's a condensed town, only about four miles across...but we have about 80,000 people here.
That is a lot, when the Albertson's runs out of Hot Pockets and Hungry-Man dinners.
The obvious solution is to get off my dead ___ and BUY some land. Well...even ignoring the exploding PRICES of raw Montana land, the question becomes, "Where?"
As far away from people as possible? That sounds good. What about AFTER? If we have this sort of Apocalypse Now scenario...when the dust settles and the zombies are one with the Earf...there ain't gonna be no more Mobilgas.
Your world is going to compress a bit. Your workable horizons will condense to what you can cover in half a day, on the soles of your busted-up shoes.
Horses are the obvious answer. Well, horses don't breed that fast, and meantime, a lot of zombies and other mindless types will have tried horse meat, to tied themselves over. Horses are gonna be more spendy than F-250s are, now.
So. Closer to town, or far away as possible.
And what if the Apocalypse isn't what you anticipate? You expect a Night-Of-The-Living-Dead, with crazed city zombies coming at you; and instead, Ding Jong Un launches one of his glow-in-the-dark toys, with the aim of hitting the ICBM missile silo not far from here.
And he misses, but not by much. So my ramshackle hut is blown away and I'm lethally irradiated. Whereas, back here in the Big City (Montana-style big city) I could have taken shelter in any of a hundred or so concrete structures, and missed 80 percent of the radiation.
And then, after. Emergency rations, given out in populated areas. Nobody's gonna be loading a horse wagon to trundle a pallet of MREs to me, out in the country.
And on and on. So...since I can't know...I'll just leave it to Providence.
If I bug out, it will probably be with the truck, with my bug-out bags, with a couple of cases of MREs, and some water. Haven't decided where yet, but there are a couple of ghost towns not that far away...ready-made structures, if not so comfortable, at this point...
