Are their trees sort of equally spaced? If yes they were likely planted. As such, if they grew there others in the area may have also planted sugar maples. Ben Franklin tried to get the colonies and the states in the early years to establish maple sugar as our source of sugar so the US didn't have to import sugar. In those days the government actually paid farmers to plant sugar maples roadside. Maybe someplace near you there is a row of mature roadside trees to get permission on. We have several back roads in central NY that have them, mostly big old trees and most might possibly be from those days. If you find some, find out who owns them and make a visit. While you might get turned down most of the time, eventually someone will lease them to you.
In the past I leased trees like that and the owners actually asked me if I was interested, but only after I had done it a few years and had some free newspaper exposure articles. I no longer do on most, because they were rather small numbers to collect from, my biggest was 99 taps, 60 roadside on gravity tubing and 39 yard trees on buckets. The one remaining one has several roadside trees on vacuum, along with about 8 acres of mixed hardwoods, predominately sugars for a total tap count of almost 500 taps.
To me, it seems like tapping the end of Feb. would usually be rather late for your location. While we didn't get any until Mar. 27 this season, more often than not, we are collecting in early to mid Feb. and we are in central NY, significantly farther north than you.
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
