CSS issues with logo and header

[Wimbledon]

Here is my new forum:

http://www.dodgedartcentral.com/forums/index.php

The default CSS for the .logo is:

min-height: 100px;
margin: -20px -20px 0;
-moz-border-radius: 10px 10px 0 0;
-webkit-border-radius: 10px 10px 0 0;
border-radius: 10px 10px 0 0;

The default CSS for .logo img is:

margin: 20px 0 0 20px;

As you can see, there is unwanted space above my logo currently. I would like to shrink the height of that header area by about 20px or so, so that the logo sits flush with the bottom and top of the header. I am not sure what CSS changes are needed.

I tried changing the "min-height" in .logo to "max-height" and "height", but those just moved the logo downward. Can you help me with the correct CSS?
