I'm hoping this link works. If you are looking for free parking in Woodstock, and don't mind a short walk, Mountian view parking lot on Rock City Rd is available for free parking. It is about 500 feet or so ( a short stroll) away from Maple lane and Mower's Saturday Flea market. the google map address is for Moutain view Studio which is behind the parking lot.
IF you want to search and have a map, search for 7 Maple Lane, to Mountain View Avenue woodstock NY.
See you at Mower's Saturday market in Woodstock
