FYI: There is a webcam in Eureka that I've watched numerous times over the years and it's right on Main St. It pivots around every 15 seconds or so to give you different views of the area, but there's a good chance for dot-stalkers to become real stalkers for a few moments if you're so inclined.

Thanks for that link jj.
A few years ago there was talk of compiling a list of camera links along the route.
Here's a few more that have been collected - - add to the list if you have any more.
