Some items I noticed:
The lodging header link is broken.
The gear header link goes to an older styled page
I don't see a drop down box to change styles.
Somehow when navigating, I was brought to your backend login page.
Forums still have the old header design so that could be confusing for guests switching between the main content and the forums.
I've been working on my own site recently with an eye towards mobile. It is amazing the things we currently/used to do with web pages that just don't work with mobile. It is eye opening how long the web has already been inconveniencing mobile users and how radically sites will need to continue to change to make it work well for everyone.
