What time did you get there Joe, at this time of the year after dinner can often be the best time. I used to fish a very hard water for big roach, I wouldn't expect a bite until after dinner, and then I'd maybe only get half a dozen or so, but worth the wait for roach over a pound. The strange thing though, if I went after dinner it wasn't the same, it was though they were sat there watching the 3 or 4 maggots going in every so often, then deciding when to have them.
