Phoenix, it’s good you’re prepping/thinking now about SHTF and travel irregardless of what you end up doing. May help in situations that are unforeseen in the future. If not already have battery operated emergency radio that you can monitor emergency services communications. If you have a smartphone (& it works in SHTF) there are emergency/disaster services apps that can help stay informed of what’s happening — Examples:
My wife and I are staying on Kodiak Island this week and next and I share your concern but don’t worry because, as you’re doing, I’ve taken a handful of precautions….alternate maritime transportation, friend is bush pilot, good kit etc. Also big fan of satellite phones and we and family members back home have them. Perhaps, if budget allows, check into it.
Other than communications — wilderness first aid is good training and definitely firearms training if you do not have already. Selco’s SHTF School online course is helpful. Work on developing that mindset.
PS North Dakota can have serious weather conditions. Get to know ins-and-outs of the climate you’re in.
