Laying down radials....the water is only 2ft deep but the mud is 4ft once you get out of the mangroves. The tube and a push pole allowed me to float over the mess. Purists will say that the skin depth of salt water at 3.5Mhz is only around 6", and I'm wasting my time laying radials in water any deeper than that - but I had the wire, so what the heck. If nothing else, it gives me "mental" gain having the wire out there. Yes, I look like a moron. But it worked.
