Hitchhiking in the united states can vary from state to state, but generally it can be superb,simply due to the long rides. Howeever i strongly recommended that woman or even man, do NOT hitch alone (every thing can happen, you know…).
A sure way to of getting long rides in relative comfort and at speeds in excess of general 55 mph limit is to ask for rides all truck stops. At Union 76 truck stops there will often be hundreds of trucks going to all parts of america. Just ask the drivers in the canteen. By using this method i managed to cover over 1000 miles from Mexico to New Orlean with only two rides. Truck stop directories can be obtained free at all truck stops.
