I have been riding alone off and on for about 40 yrs, farthest I have gone is maybe 35 miles away from home as a kid at about age 10 and ona pedal bike, on a fishing trip
I have never feared going off alone, been dropped in Alaska by float plane and left for 10 days to 2+ weeks
I think many folks over think things and well, many folks just don;'t have any real skills or common sense too LOL
riding alone be it on ATV's, motorcycles, or what ever(even hiking or walking) accidents can happen, and its up to you if the risks are worth the adventure or not
going prepared for basic things helps, but I have also been in an accident in middle of no where all alone, that left me waiting for many hours till someone randomly passed by to go get help
I wasn't able to move or for sure help myself, I didn't walk for 3 months after that one, so the risks can be VERY high pending what your doing,
but BAD accidents can happen ANY WHERE, ANYTIME!
if you live in a bubble, it too can bust
My view has always been based on IF , I am willing to take the risks, and if I CHOOSE to, then IF something goes bad, I don;'t CRY about it, or blame anyone but myself
I seldom carry a phone with me either, grew up in a time before everyone had them and managed just fine?
one thing I will admit, as I got older I have taken less risks to a point, partially I think due to I have taken so many over the yrs, I just don;t feel the need to test what all I can do, been there done it kind of views these days
but Nothing wrong with riding alone if you enjoy it
NEVER having to wait for others to show up, them NOT being ready or prepared , going where you want to and stopping when and IF you want
riding alone has a lot of perks IMO
but do admit, having a good friend to ride with is just as enjoyable, there just harder to find with like minded ways!
