Google maps:
Find the location on Google maps. Make sure you click twice in the area where the roundhouse is to center the map on that point. Don't go into street view mode. Then click the "Link" button in the upper right.
Copy the line in the "Paste link in email..." field and paste into your favorite word processing program. It looks like this (I removed http so rr.net wouldn't turn it into a link):
maps.google.com/maps?hl=en&source=hp&q=buffalo,+NY&ie=UTF8&hq=&hnear=Buffalo,+Erie,+New+York&gl=us&ei=qsloS5jQONHYlAfYxMyJCA&ved=0CA0Q8gEwAA&ll=42.828285,-78.807678&spn=0.001863,0.002291&t=h&z=19
Find the "&ll" part and the lat/lon are right after it. From above: 42.828285,-78.807678
You can pass these around, paste them into Google maps later on, Google Earth, your favorite mapping program, etc.
