Ah, I believe I have seen this Jetty by accident. We took a left from 61st street and went all the way to the end of Sea Wall and saw a few cars parked on this little steep hill on the left. Or maybe that is not the right one. But I got a pretty good bearing where is Jetty is at.
Thank you for all your HELP and we will see you there in the SPRING and SUMMER run. "Whatever run up there, we will try to catch it"
