I use to camp alone several years ago. Had a Flagstaff pup back then that I really enjoyed camping in, but my wife didn't like it mainly because of no bathroom. My favorite time was in early spring when the nights were cool and I could open up the bed flaps at night.
I would fish during the day and spend a quiet evening around a campfire.
Usually I had caught enough fish that by Sunday noon people would start showing up for a fish fry....my parents, my wife, my daughter and her family.
I was usually worn out by the time I got back home, but I loved it.
I have a different Flagstaff pup now, but never go out alone anymore. That's a whole other story I won't go into, but I do miss those days.
