I don't know whether you have hills in Florida...but if you do hunt places with hills or mountains: Try to avoid skylining yourself as you traverse along the top of the bank. Deer also try to avoid skylining themselves, by having most of there deer trails somewhat below the skyline.

If an alarmed deer stomps one of his or her forelegs into the ground while looking at you...along with or without snorting --- Is releasing alarm scent on the ground by it's gland between his bottom hoof. I forgot the name of the alarm gland --- Maybe ole' timer can enlighten us on the name of the alarm gland.
