But remember for best results only swing one at a time.....

I know some piers around here have wheels on the ends, car tires, perhaps a ladder with some bike tires or somethign would work. These boat piers are hauled out before winter, probably by some sort of vehicle, but the idea is what I'm suggesting...

depending on your situation, dropping some good size stone might be a better idea...

haha in full hunting gear and with a weapon the use of a rope swing is unethical and dangerous use a ladder you dont even need a new one buy one cheap on craigslist or something I use it by my spot works wonders.

you can cut plans to go across the ladder when its flat so you can walk straight across it safely

ladders arent meant for carrying side loads like that. many an aluminum ladder has been used incorrectly often with comical and sometimes tragic results. Do the hip waders if the water isnt too deep.
