It's sorta like asking a dedicated fisherman where the best fishing spot is.
Amen! I can attest to that! After I spend hours pouring over nautical charts staring at all the depth numbers looking for possible spots that are not listed as a fishing spot, I don't want to see a boat belonging to a fella I took previously fishing over it.
For this reason, I better not catch a guy smugglin' a GPS onto my boat.
