Last summer on day 68 of a scheduled 85 day wilderness paddling trip in the middle of nowhere, I suddenly experienced what I believed were stroke and/or TIA symptoms. Being well north of 70 in age, it is not that unlikely. Having been involved in SAR for decades, I am always hesitant to call out a full calvary response for an issue that I can potentially mitigate myself. (like most SAR members I have been to my fair share of "severe hangnail" types of callouts...) So I simply "inreached" one of my contacts in Yellowknife who organized a consult with a physcian and after some back and forth messaging, my contact ordered up a helicopter ride out (my tab). I was in hospital getting a CAT Scan well within the stroke treatment time window. As blacklbzbeauty mentioned, the satellite is always there 100% of the time and can always be counted on. I get it that radio is everybit as good when available but for this trip, it was not an option during most of it. Turned out I damaged a nerve in my ar*e from months of sitting in the kayak, all good now.....
