Oh, gjorg... I'm so glad you asked this question!
I hitchhiked a lot and all over the Western USA from age 15-19, until I bought my first car... and then occasionally, as needed.
I had many GREAT rides with wonderful people, for the most part, but also some creepy ones, where I actually asked to be let out at the next corner, with some sort of excuse, like I left something behind that I needed. I was offered my first blowjob, my first male 3-way and first toke of pot while hitching... Car-Jacking meant something else back then... lol! I met people who became good friends and travel buddies. I was invited to nice homes for a good night's sleep, meals and a shower, shared campsites and motel rooms and got odd jobs for cash, that helped me on my journeys.
Sometimes I had to camp out overnight at freeways entrances or truck stops, but, eventually, I always got a ride. It might have helped that I looked like a skinny version of Clark Kent! And, I always had cool new music for them to listen to... and always politely listened to what they played.
Interesting note: I was surprised by how many single women picked me up, but, almost all of them had a large dog on board. Smart women. But, I think that I presented myself as a safe, if not, FUN, passenger.
My most recent experiences were due to car trouble or needing to return home before my expected departure times, and the lack of public transportation in remote areas of North Central Washington State, and Northern California. One town practically adopted my best friend and I when we had to hitch because of my starter needing to be replaced. They put us up in a Bed N' Breakfast, bought us dinner at the local cafe, and made long distance phone calls to get someone there to take care of the car and put the two of us back on the road.
Yes, Times have changed... Watching SUV after SUV whisk by... often in the rain... sometimes I had to wait for HOURS, per stretch, and was only picked up by icky, proselytizing, Evangelical "Christians" or packed carloads of kindhearted, sympathetic Mexican migrant workers in tiny, beater Toyotas, with really loud, great music, (and chips and salsa)!
I may have been risking life and limb at times, (drunk drivers, for instance), but, I will never regret the incredible people I met and the experiences I had, good and bad.
