Funny you mentioned it. Two weeks ago when the actual hunt took place I did need to use them. After lunch I went to start the truck and head to the stand, and can you believe the battery was dead? Thankfully one of those evil dog hunters stopped and gave me a jump. He then had the audacity to send us to a good spot since we were new to that area of Eglin.Didn't have to use those custom jumper cables this trip ?
