hi there!
i've only traveled by train about from NYC to DC so that's not a long trip, really.
I have travelled by bus...
across the country(USA) back then in '79 & 2/3rd across in '80 -
with a
2 week get off/on as much as you want pass!
I'd say
except for the bathroom part yuck
you'd have a great time because
in general Trains are more comfy than Buses.
I watched the landscape go from the abundance of green and hills & valleys (in PA, Ohio, Missouri) to more flat by southern Missouri, Oklahoma & then pan handle of Texas (at night) to wake up to my
first goal:
seeing the scrub, and amazing, sculptured rocks in beiges, tans, rust oranges, pale & medium grey-purples, etc lit reddish at sunset of New Mexico & Arizona- the High Desert! WOW!A Dream come true.
I met nice people on the bus.
With a bus we'd get off at the rest stops and usually the bathrooms in
those places were better than the bus one. So we had that advantage.
I'd say
definitley explore it....
and
also see if they have a get on & off pakage that might be better than just sitting on nthe train thew whole time, if that can work for you.
The only time i stayed on the bus was going the long distances to get elsewhere (WHILE enjoying the changing scenery)
NYC - Flagstaff, Ariz to meet up w a friend/ then after we were done, I went on to San Francisco, & then back to LA (for instance) to visit a cousin, then back to the South West in several areas again, before heading home.
IT was incredible!!!
I'm
very happy/blessed to have the memories, photos and
yes I kept journals, too, with sketches (since I'm an artist) as well as my thoughts etc.
One reason I did this was back then there was concern on how industry etc was encroaching too closely to the National Parks etc SO i was like
'... I have to go NOW, before it's all gone [marred...] !'
With in say 3 -4 months I'd saved up enough, researched enough and went.
Plus I had become scared of flying, so Europe, and anywhere even further away was out of the question for me then.
I hope this INSPIRES you further!
Let us know what you end up doing!
