IE6 Compatibility Problem

I am new to CSS and am having some difficulties getting my site viewable in
IE6. IE7 works fine and Firefox works good (only a few hiccups with Firefox). I
was wondering if someone could take a look at the site and tell me what I might
be able to do to fix it.

It appears that a lot of my content just does not show up in IE6 or is shifted
down quite a ways on the page.

Here is the site. http://www.huntclubfarm.com

Any help would be greatly appreciated.

Regards,

Nick
