A Minnesota couple’s fast thinking proved to be a lifesaver when they assisted in warning other campers of the devastating flash floods that were sweeping through central Texas.

Following the devastating floods that occurred in the Guadalupe River area during Fourth of July celebrations, at least 104 individuals have lost their lives. Within hours, a month’s worth of rain fell, causing flood levels to rise to 26 feet and washing away cars, cottages, and mobile homes.

Those caught up in the pandemonium included Minnesota seasonal campsite workers Lyle and Sue Glenna. However, instead of concentrating only on their own escape, they used valuable seconds to warn others, probably saving many lives in the process.“They were able to get into their truck and honk a warning out to a lot of people at the campground, which definitely helped some people make it out,” said their son, Wes Glenna, speaking to CBS News.
