How about a simple trip up to Croton, anchor and have lunch, lounge a little and enjoy the peacefulness. I would wait another couple of weeks before venturing too far due to the debris still afloat. We had a nice ride Sunday up to Kingston but I wasn't relaxing at the wheel, saw more than a few scary pieces of driftwood.
If you do go to Newburgh you actually have a choice of 7 different restaurants, and you can dock at Front Street Marina or Torches - if you eat at Torches!
Have you even been told about going in and out of Piermont, paralleling the jetty as you go out because of shallow water? Good luck working on your admiral, do everything you can to make the first couple of outings pleasant and trouble free.
