To whom it may concern in Rhode Island, there are 2 Appleseed events in eastern Ct in the month of August.
August 8-9 at Pomfret Rod and Gun. About 15 miles from the border, easy to get to and the club is going the distance to have this a successful return of Appleseed to their range. https://appleseedinfo.org/search-states-location.php?locationid=256&id_event=3961
Bozrah Rod and Gun will host an Appleseed on the 29th and 30th. https://appleseedinfo.org/search-states-location.php?locationid=45&id_event=3863
By the schedule it appears that these 2 shoots are the closest distance for those in the Ocean State. Hope you can make one.
The Pomfret shoot has been moved to October 17-18, so there's a chance to catch one not far over the border.
