I've never been into going to Prospect, I don't know why, I just don't ever go there.
I caught one trout at Elk in the mid 80's that far exeeded that 23 inches. A very memorable fish. I caught him right in front of the reed bed just to the north of where the fishing pier is now. The thing looked like a coho for christ sakes, it was huge. LOL Anyway, I had a plastic pan in my boat with water in it that has the inches marked off across the bottom of it. The bottom of the pan is 22 inches, this fish was laying in the pan and his tail was curled up one side, his head up the other. A memorable trout from there for sure. [8D]
I've seen a few similar to that come from Langford lake as well.
Also, I wanted to mention that in my circle of friends, there are few of these fish bonked. I take maybe 6-8/year. Enough to have some smoked trout for x-mas is typical. I take newbies out on occasion too that may kill their 4. No biggie, they go fishing once every 5 years for one day with me, maybe. I think most people are pretty good, I don't see nearly as much abuse as I used to but there are still a few of those dudes out there for sure.
Cheers,
Jim.
