I have hitch hiked a couple of times.  Have you ever been hitchhiking?
1_Wizard
I like asking strangers for a ride.

When did hitchhiking become commonplace?
1_Wizard
I do not know, but I prefer the free rides vs the non free rides.
0_Apprentice
I agree with that!  Do you think it is dangerous to hitchhike in the present day?
1_Wizard
As long as you use the proper hand signals you should be ok.

What are the proper hand signals?
1_Wizard
You just extend your arm toward the road and stick your thump upward.

Oh yeah!  I know that one!  Is there any other etiquette that I should be aware of? 
1_Wizard
I have no idea but there are very few places in the world that have laws to restrict it.
