GUNTERSVILLE, Ala. (WHNT) — As summer temperatures rise across North Alabama, many people are heading to Lake Guntersville to cool off and unwind. For a group of local veterans, time on the water offers something even more meaningful: relief, healing and connection. Army veteran Mike Geissler and Air Force veteran Jeff Martin dedicated more than five decades of service between them to the military. Now, they say the lake has become a refuge.
