I've been focused on hunting for the last two months and haven't fished at all. I decided to fish St. Marks on Saturday (11:00 low tide) with a plan to do a little sunrise topwater and work my way into the creeks 2-3 hours before LT. Unsurprisingly, no bites and no signs of bait or activity on the flats, so I worked my way east to get into a creek. Between the Northwind and the tide, I could not float my kayak into any coves or creeks, which really surprised me. Then I decided I would drag the yak into one, and I realized that I had made a serious mistake a few seconds after stepping off my yak in about 3 inches of water when I went knee-deep into the muck. I was shocked at how deep it was and how very difficult it was to get my leg out. It was a lot of fun trying to keep one leg on the yak and getting the other leg out. I tried a few more spots but didn't find anything I was willing to risk walking through at that point. In retrospect, I probably just got really unlucky with the spot I chose to step off into.
At this point, I was pretty dejected and worried about getting stranded in a cove or creek, so I decided to look at another spot. Paddled back to the lighthouse only to see nothing but mud for about 100 yards that I had to slog through with the yak to get back to the truck. That sucked... a lot. Then I drove out to Wakulla Beach and saw what looked like 300 yards of muck to get from the parking lot to the water. I decided it would be a good day to get some chores done.
I didn't even get a hint of a bite, but I did get lots of opportunities to learn about Winter tides in Apalachee Bay.

I'll look for some alternative launching points in some creeks for the future or stick to high tide.
