What I really want is to do both hitchhiking and freight train hopper. But for freight hopper, I find that in order to do that, I will need to keep my ears on things around me. Of course, I can still do that. But is lots of work, especially for my eyes where I ll have to be alert all the time. Not to mention, lots of risks. I ll need know where the safe train yard is, their schedules, where to jump in and out spots. I ll also need to be aware when they will put the stuff in the boxcar without hurting me. When I ll need to ran and duck if anyone suspected someone is out there in the yard. Too much but it still sound awesome, don't you think?
Now if I want go from hitchhiking to freight hopper....Or freight hopper to hitchhiking...I wont be able to know how easy or hard it will for me to across between the highway and train track, plus the trespassing and above of all, its illegal. Its not worth the trouble.
So I decided to stick with highway.
