I appreciate the help. I was back in behind the Froggy Dog about 3 weeks ago and I did find a small ramp nestled in behind some houses. I think they may have been townhouses. But that ramp wasn't suitable for a trailer. It looked more like it was setup to make it easier to launch cartop boats, canoes, kayaks and such. Is this the ramp you are talking about? If so, I won't be able to launch my 17' boat there.
Thanks,
Ron
