When I travel by coach, I try to find a window seat and sit by myself. I will put things on the aisle seat, but remove them prior to the next stop, so if any new passenger wishes to sit in that seat, they can. Other than instances where I have had to board coach seating in which assigned seats are the rule of the day, I usually end up by myself. I am in the largish range, 250+ pounds, but on the occasions where I have had someone in the seat next to me it has been no problem. On one occasion, last year, while returning to Spokane from Glacier Park, I had boarded at East Glacier and grabbed my customary window seat. At Whitefish, a large amount of passengers got on, and a young girls (in her 20's) took the seat next to me. Unfortunately for me, she proceeded to stretch her legs out on the footrest, and sleep the entire way to Spokane. I say unfortunately because it wasn't very long before I had to use the restroom. But with her stretched out and my being a klutz in the best of circumstances, I elected to stay put, hoping I didn't have an "accident". I managed to "hold it" (sorry for the potty references!) until Spokane, when I made a break for the bathroom at such a sprint that I doubt Usain Bolt could have beaten me. :lol: That's the downside of my window seat habit.
And when I returned to Spokane from the Seattle gathering a couple of years ago, there was an announcement made to the effect that there would be a large amount of passengers boarding at Everett, and that every seat in the coach would be filled. The conductor went on to say that no single passenger was entitled to two seats together and that if anyone wanted to sit by themselves, they could purchase an additional seat. I must look uninviting (those who met me at the Gathering feel free to use your own judgement on that
) because no one occupied the seat next to me during the trip to Spokane, despite a "full" train.
And, finally, my airlines story: A few years ago, while flying to Seattle, I was at the waiting area for our gate in Spokane, and amongst the passengers was a rather large woman. She was larger than a woman I knew from my hometown who weighed in excess of 500 pounds. As I said earlier, I'm not exactly skinny myself. I know this sounds awful, because it is, but I found myself telling the Lord that I would do anything. I would go to Zimbabwe to serve as a missionary, anything, so I wouldn't have to sit by that large a woman. He answered my prayer! I still haven't packed for Zimbabwe, though.
Bottom line to all this: I prefer a window seat and prefer to sit by myself. If that isn't possible, so be it. Like Trainman's Daughter said, I need any passenger next to me to be aquainted with soap (and Right-Guard). Other than that, I don't care, at least on a train.
