The two major health hazards for visitors to the German Hill Country both involve water, too much of it and too little of it. Flash floods can cover roads with up to 10 feet of water during especially severe thunderstorms. Low spots are signed to indicate the depth of water over the road. Never drive into running water. Every year some motorists die because they drive into a flood.
In the summer, be sure to stay hydrated. The most severe effects of dehydration usually hit those in the best athletic condition. Remember to drink cool, not ice-cold water regularly, and to protect against the sun.

Despite the location in the "German" hill country of Texas, you do not need German to communicate. On the other hand, German speakers will find Gesprechpartners in Fredericksburg, Walburg, and other smaller communities, especially among older persons. Many school systems offer or in some cases, require 12 years in instruction in the German language.
