I'm working on it for myself. I have the file for Croom almost done and will distribute once I double-check a few areas where I think I gave myself some bad data. I'd also like to get labels for all those little named features and trail sections that people recognize by name but aren't marked on any map. I think I have all the official trails and probably accidentally some of the unofficial ones. The fire roads are marked on the FL-Topo maps that are freely available and atleast seem to be accurate where they cross trail. I can't really comment on whether they're accurate elsewhere. I'd like to find traces of the horse, hiking, and ATV hunting trails to have as references for those times where you need the absolute shortest way out or for those "wait I think I made a wrong turn, where exactly am I," moments.
I have several traces of most of Alafia. I think I'm just missing some of the double-track, definitely Gatorback and Moonscape, maybe the hard options of Rollercoaster, and that little piece sticking off the south end of North Creek that goes past the campgrounds to to the southern part of River Loop. I think I got all of River Loop last time I was out there including the parts that still had ankle deep mud, but I really need several traces to take the average and have a good map since the tree cover doesn't make for terribly accurate readings especially when the leaves are wet (water reflects and refracts GPS signals).
