Good thing you had a fishing pole. Hope you had GLOVES, too!!
You know, for those really memorable experiences (not the outhouse one - I'm talking about the mountain campsites), I took a class in meditation one time, and they taught us how to plant those memories firmly into your mind, and to bring them back whenever you want, as vividly as if you were there again.
All you have to do is be very conscious of where you are, of the sights, sounds, smells, temperature, etc., and then put your finger and thumb together, and tell yourself that you will be able to recall that moment whenever you want, simply by putting your finger and thumb together again.
Don't laugh. It works!
