Details (RL read field instructions carefully):
Leave the Riverhead waterfront at 9:00AM for a ride to Mattituck and return. For those people who like to ride bicycles - a double-header. You can also do the 4PM ride out of Mattituck. After the morning ride anyone wishing to freshen up/shower before the afternoon ride and/or the Custer Institute visit can do this at my estate in nearby Flanders. - at no charge - er, bring ur on towels.
Get to Riverhead waterfront by traveling east on Main street and making right on McDermott. There is a church on your left on Main Street before McDermott.
