Started at Green Pond Trail Head and headed North. As reported, the trail has some pretty big bumps and a few holes, usually near the edge. With the limited traffic on the path, it isn't difficult to avoid them but you do have to keep your eyes on the trail. On 3/28 there was quite a bit of tree trimming and brush consolidation in the 10 miles between Green Pond and Bay Lake and some heavier equipment was staging at the State Park garage near Green Pond so maybe they are going to fix it this Spring.
The 10 miles between Green Pond and Bay lake is a very nice mostly shaded ride through timber with swamp land on both sides. There are 3 bridges about 2 1/2 Miles North of Green Pond which provides a place to watch alligators (this is mating season so you see some but there's a bunch more as the grunt and talk...), enjoy the birds and quiet serenity. At Bridge 2 that day, there is a 10+ Foot alligator nesting with her (soon to be) baby alligators.
North of Bay Lake is very nice and shaded for the 4 miles we traveled (Total round trip of 28 Miles).
Some call this trail 'straight and boring.' I'd suggest that it is quiet and serene, and, because it is straight and wide, you can spend most of your time enjoying nature!
