Worst day fishing in my life and it wasn't because I was skunked

[Almaink]

So I get to the D&R Canal and there is only one parking spot and no body fishing. I park and move to the hole on the low side of the bridge and catch a nice 14" on my 5th cast. As I'm reeling it in a small station wagon pulls in and lets out a women and a kid. I figure they are going for a walk and Dad will pick them up later, wrong! Dad parks illegally blocking the two cars that are legally parked and here comes another vehicle that also parks illegally and out gets an older woman. They guy pulls a few poles and a tackle box out of the car while I'm unhooking my fish and sets up 5 feet from me and casts right in to the hole with a bait set I'm fishing with spinners. When I say to him, "You have got to be kidding me, are you really setting up that close and casting into my spot?". He says why you gotta problem with that? And I say Yes there is 62 miles of canal and you don't need to set up right on top of me. His mother or his wife's mother starts in with the free country crap and I pull my stuff and move after telling her to go look up fishing ethics when she gets home. Ruined my whole afternoon. How can people be so rude? They had a kid with them too and that what really bothered me, teaching bad manners to youngsters. I'd never set up on someone like that, and my kid wouldn't either.
