HIGHLAND MILLS, N.Y. –Throngs of people smiling under sunny skies after days of chilling rain, a festive maypole, live music, rows upon rows of vendors hawking their wares. This was the scene that welcomed Gavin Bone and Janet Farrar to the ninth annual Beltane Spring Festival put on by the owners of Brid’s Closet in the gently rolling landscape of Palaia Winery. The pair were actually on hand for several days, offering workshops, running rituals, presiding over a wedding beneath the ribbons that hung from the maypole and hummed like a flock of the eponymous birds, and talking about their new book, Lifting the Veil. The only potential cloud that might have been cast upon the events was the fact that copies of their book had not yet arrived. Signings were taken off the schedule.
