Hedge your bets if you have a BOL by having some preps at your in town residence & emergency items in your primary vehicle. It may well mean you have to ride out the initial Big Event with what you have with you, hunker down a bit and let the first die-back occur, migrate to your nearest prepared location, repeat process, etc. It may not be perfect and there is no guarantee you'll make it to where you want to be or even that once you're at where you want to be you have much more time to survive, but something is better than nothing, and if it allows younger generations time to survive in the new environment that is at least something worthy to aim for as well.
I think he is right that if you CAN live at your BOL, then you should. Its just one less logistical problem to be overcome. If you are not there, during the "big event" your BOL may be discovered and raided before you arrive. I worry a bit about that in our scenario. The greenhouse and PV are conspicuous if you live in the neighborhood. As I meet people I say I am the guy with the solar panels and the hippie dome and they all know where I am .. . They work great as "don't bug me, I am obviously liberal" camouflage, as long as folks don't know better, and there and the neighborhood is rural, so in general folks look out for one another- but there is no guarantee that will continue after an EVENT. . If things are really bad though, they see food and power and may loot those while leaving my crappy vinyl sided double-wide alone. I may have to pull the panels down, and break a couple of poly panels on the greenhouse to make it look like its already been "hit" - but I may not get time to do that if the event is sudden and I am trapped in "town" - of course, the new "town" I am in is sub 10,000, and not 100,000+, and I am 45 minutes away from the big population centers. I am not so much worried about the EMP pulse (which would kill my panels and inverters too!) and the greenhouse itself is unlikely to be massively damaged.. people will break in and raid the crops, they don't care about the structure. But a Martial Law with travel restrictions would make it very difficult. The only way around such roadblocks is on foot, and I am too far to hoof it with children. Maybe on horse back. Maybe. They of course can't watch every little jeep road, but I may have to wait till late spring to get through on those.
However there is something to be said for some degree of diversity. If I had unlimited funds,I would be prepping a place in Denver, a good sized farm outside of Denver, a place in the mountains - or maybe two in different States and one or two places overseas. Options are good, even if there is a risk of an option falling off the table. In Argentina a lot of rural folks had to move into the cities to find jobs, and supplies as the trucks didn't deliver to rural towns anymore. Ironically, in many cases, the cities/town were safer. Criminals are more bold when you are by yourself and no help is coming. Even my new house "in town" may turn out to be too rural.
As he says in the article - wherever you are won't be ideal for every scenario. You do what you can with the constraints you are under, and make it work the best you can. This isn't a game,there are no rules and "winning" means you survive and possibly even prosper and thrive.
