In a phone call, Matute highlighted the difficulty of obtaining access rights to subsurface property: Since a property owner has rights to the land beneath their house, tunneling below private property requires what's known as an easement, the permission for a third party to operate in the underground portion of the land.

The best all-around saltwater fly line is Rio's InTouch OutBound Coldwater series, and an intermediate fly line is ideal for subsurface fishing at shallow depths, and by extending your leader (the nylon line that runs between your main fly line and your fly) you'll have no trouble fishing topwater flies, too.
