It appears that SWFWMD has recently hung new 'Do Not Block Gate' signs on a lot of these old gates along SR471. It seems odd that they would go to the expense, many of these gates haven't been used in years judging from the looks of the old roads behind them. This is one of those. Happy hunting!
We averaged 300+ positions to get the coordinates for this cache; but as always trees, satellite alignment, the phase of the moon, etc. can cause issues. If you have difficulties use the hint provided.
