Can I see a map of the site? Or a map to it?

Most, but not all, sites have maps available. Once you've selected a site, click on the "maps" link near the top of the page, underneath the site title (as shown below).
Note : if there is no "maps" link here, that means that maps are not available for this site yet.

Maps may be in a variety of formats, from static images to .PDF files to embedded Google Maps (as shown in the screenshot below). Embedded maps, if available, allow you to zoom in/out and get driving directions to the site.
