WhitePages / YellowPages - Hmm... I wonder what this could be... :)  You can look people up by their name or address.  You can even do a reverse search - look someone up by their phone number!  Just another tool for us cyberpimps.  :)

The Ultimates - This is just a must use site.  Any time you need a phone number, whether it's for a person or a business, you can look it up here.  You can also do a reverse search which is when you enter a phone number and it tells you who that number belongs too.  Extremely useful site.

UPDATE! 08-20-01 - TerraServer is no longer free!  I tried using it a week or two ago and it is not a pay-per-use service.  There's still a free section, but it wasn't workin' right while I was there.  :(

Men's Health - This is a great web site to compliment a great magazine.  My top two recommendations for guys to read are Maxim and Men's Health.  Get informed and you can't say you didn't know.  :)

General Cinema Movie Theatres - Uhh, I don't know much about theatres but this is very helpful when I'm looking to go see a movie.  No more 777-FILM and listening to that stupid guys voice!   Straight to the info I want.

Cinemark Theaters - This is great because you can get movie times, buy tickets, or even print out all the movies at a theater and take it with you so you can argue about what to see with all of your friends.  YES!
