Live and learn and that is the important point, that you come away alive.
Sure there are going to be lots of snipers with "helpful" criticisms but I admire your honesty and will publicly admit to some pretty dumb moves myself over the years, usually announced by the statement "hold my beer and watch this".
I don't offroad too much on the big road bikes but I take my Rokon and Argo down some nasty trails out on the harsh Canadian Shield forests around my hunt camp so I can identify with your experience. No cell service where I go and it may be days before another person shows up on those trails.
Glad your okay and that you shared.
PS. Get a SPOT Messenger, it will give you and your GF a great deal of comfort when you (as you should) take another, but better prepared stab at these roads. You will hear that they are crap...from people who I suspect did not read the manual. I have owned one for several years and although never used in an emergency, can state from experience it does work (tracking, I am okay messages, etc).
I also own a satellite phone, one of the Globalstar models. They sell a cheap plan because the have spotty service due to incomplete satellite constellation but it does work if you wait for the birds to arrive and there is an upside to 2 way communication.
Either way, sat com of one sort or another is great.
Honda ST1300 with Hannigan Super Sport sidecar (Hondagan), Ural Gear Up, Rokon Ranger and now an Argo, WTF is wrong with me?
A Brit named Billy once said something silly; he so wrongly concluded that Ural deluded.
