You should be able to find "decomposed granite" in New England. It should work as well. Doesn't pack down as well as limestone fines, but should cut the dust. FYI, limestone fines is a mixture of limestone gravel and dust from the quarrying process - usually the dust is washed off to get "gravel". Different parts of the country call it road base, flex base, crusher run, et al.
