It's like this..
I'm trying to get in while the fishing's still good and hopefully before the bugs are out in full force. I'm certainly open for alternate dates, but my reasoning is to settle on a date early and work to that rather than to leave it up in the air too long.
I'll be up in the park on the April 30 - May 1st weekend for my annual spring trout season opener. The following weekend's Mother's Day (May 8th), so any plans are scuttled if you value your hide. That leaves the next weekend, the 13th.
Let's see how interest develops and go from there, but for now, let's work towards the 13th.
Even in wind and rain, we manage to have a great time...
