I know it changes from year to year, but does anyone have an approximate time as to when the Mayflies usually start up enough to damper the fishing? Every year we plan a trip for the early part of June, and I'd have to say that's always the worst time! We were toying with Memorial Day weekend. I know earlier is even safer, but trying to hammer down a date that will work best for the whole group and Memorial Day might be it.
Thanks,
Sean
