If you could get an exclusive, no one else could fish it, and the area was large enough, I'd have to consider it. You said 3 farms control 15 miles? How much does he control? Tell him you want to survey the spot first, maybe even fish it before putting out the money. If it looks good, then talk turkey. You could get guys like me to pay a fee to you to fish it with you too !!
Maybe talk him down to $500 and draw up a contract so if you found other's there or signs of others fishing, he'd have to refund you. At $500 it's about $10 a week, not much for an exclusive lease. I know a guy who leases the rights to a golf course, has access to the Little Miami river, and bow hunts deer there. He can legally run people out bank fishing the river if he feels like it.
As for this
Nope. I'd take that $200 and buy me a float tube or something so I could float down the river you wanted to rent me and flip you off
You don't need a float tube to do that !!
Flats, his section of the river has been worked over by his trotline using relatives, so save your money or send it to me as a downpayment on this bridge I got for sale in Brooklynn, good access to stripers there too !
