RE: Landowner permission
When I was a kid, living on the farm, my city buddies found a farmers pond outside of town. It was full of big blue gills and cat fish. They described how they had to outrun the farmer on his tractor when he busted them. I went there one day and started weeding one of his 40 acre bean fields. When he asked me about it, I just said maybe he might let me fish that pond a few times when I got the beans weeded. I had the run of his place for 30 years.
