Don't know if anyone else does this, but my traveling mate and I would always draw a little on/off switch on the back of our hitching or panhandling signs. We'd turn the sign on to make it work.
It was really silly, but we did it religiously. I still draw that little switch on the back of my hitching signs to this day, and I repeat the whole pattern, complete with the little "boop" sound effect he always made when he pressed the on button.
I ALMOST FORGOT MY LUCKY RAIL SPIKE!!! It has nothing to do with hopping trains, since I don't hop. I was hiking around a trail in my hometown with a buddy of mine. This trail follows abandoned train tracks from the gold mining era. He picked an old, rusty spike and handed it to me. I put it in my pack when I left for my first hitching trip, and it came with me all the way across the country.
I think I'll continue to carry it until it gets lost somewhere. No use for it, just a superstition that it somehow carries positivity and good luck.
Then there's these protection beads that a forest service worker gave me in Pennsylvania. She told me that they were from a shaman, and gifted them to me on a whim when she picked me up. They are beautiful glass beads that now hang on the string that connects my pepper spray to my belt.
I guess I have quite a few superstations for someone who does not intellectually commit to these kinds of ideas.
These rituals and objects just bring me emotional comfort, even if I know, on a practical level, that it doesn't make any damn sense.
