Today is an oxymoronish day.
To celebrate Find a Train with Over 100 Cars and Count Them Day, you have to find a long enough train, but you won't know if it's long enough until you count the cars, so then you don't need to count the cars anymore, but that's what you have to do once you find a long enough train....
What might be easiest is to simply find a train that, when looking at one end of it, you can't see the far end.
If it's not moving at the time, you have two options. 1) Wait until it starts moving and then count the cars. 2) Start walking.
The engine, or engines, if there are more than one, and the caboose, if any, all count in your counting. It doesn't have to be 100+ cars in between the two.
I know that defacing the cars with graffiti is wrong, but I find much of it very artistic. Don't you?
I hope some of those "artists" are using their talents elsewhere profitably too.
