Matt I hope you get your rain 3ac of sod=$$$$
and sound like the drive in might be fun (never no you might get lucky)
GW you kinda want the pipe to be able to sink so it aint just wraping the stuff off the top of the water. The FA will pull down the pipe and grab the stuff off the bottem as well. I've been able to wrap up huge masses of coon tail all the way down to the roots. you would prolly have to glue the sections together cause once you get a good size mass of moss on the end when you go to pull it out of the pond the end piece would come off.
