It was assumed by the original owner way back in the day because the County allowed it and he told all the buyers of the 3 properties he had up for sale that it was all good. Problem was my dad and the buyers of the other 2 parcels took his word for face value(I don't think he was trying to scam anyone, I think the really thought it would be ok forever) and all ended up getting burned in the end because there was nothing in the deeds stating anything to that affect. The creek is impassable to everything accept foot traffic and even then only in certain areas. Most places you would sink to your neck before you got half way across. Very few places are suitable for putting a bridge across and still maintaining the navigability of the waterway without going to huge expense to build raised platforms to set an even more expensive pedestrian bridge across, and then you would be risking having all that sink out of sight in most areas.
