Tooltip text

Have the same map in two places (in the midst of changing the theme)..

http://www.bearriverwinery.com/info/visit-us/

The bottom map in the widget, when you click the icon where the location is, gray text appears with the location, but the map on that page, the text is white on white.

How can I make the text visible?
