These links have been useful in telecommunications and other technical classes at Champlain College. The sites are grouped by general subject and there is some overlap. Some sites will appear in more than one category because of overlapping functions. There has been no attempt to duplicate Wikipedia for coverage. It's impossible to keep a list like this up to date and it's by no means comprehensive. Apologies in advance for 404 errors. Google is your friend so go exploring beyond this list.

 Urban & Subterranean Exploration:

This is a collection of sites dedicated to the exploration of abandoned urban buildings and infrastructure. Some of this is above ground while other locations are well below ground. These are all rather dark sites, both in terms of the lack of light and in the psychological sense. Enter at your own risk.
