When I was 17, a friend and I did something very similiar to this...There was an old man sitting on a picnic table at Ellender Bridge boat launch and pointed over towards Big Lake and said "Boys, you see that storm a comin', I would not venture out".....Well being young punks we said we were just going to Black Lake and would be fine....
To make a long story short, after spending 3 hours on the levee on the Salt Ditch laying in the mud and hoping we survive, we made it back to the boat launch to find that same ole' man sitting on that picnic table....All he said was I was justing getting ready to go look for ya'll.....and smiled.....
