Hi my partenar and I flew from New Zealand to LAX, then across to Tennessee ,onto Amtrak ,transferred to a Greyhound and ended up at our destination 24 hrs later!!...
Happy to say we didnt get bored during the flights ,they were awesome. The train was surprisely relaxing too and great to stretch our legs out fully.
By all means take a good book ,something light ,maybe comedy since I found everytime I would start reading something interesting would distract me.
Definately writing material ,even if its to jot down any ideas you get. Postcards to write.
An Ipod might be useful for down time waiting too.
Enjoy !! youll get tired ,but it will all be worth the scenery , the new people, the experiences.
