Jbess,
Are you unloading at the southern most ramp? I seem to remember a concrete retaining wall that you could park the boat against(with fenders out of course). Is the wall gone?
Of course, this is also a good reason to buy a bow rider with the ladder that comes off the bow. Have your wife drive the boat up near shore and you step up the ladder with only getting your feet wet.
Best of luck,
CZ
