The posted coordinates place you at what once was the site of the River Road Covered Bridge. Built in 1910, sadly this scenic covered bridge burned down on February 6th, 2021. First clue: the replacement bridge has a posted load limit of A0,000 pounds.
Next drive north on River Road to a small parking area giving access to stage 2. This stage's coordinates are N44º 58.389' W72º 23.150'. At this point you are near the "Big Falls" of the Missisquoi River. You can get a better view of the falls by continuing to the rocks nearby (at your own risk). Second clue: at the coordinates, there is a brown sign with three words printed across the top; the number of letters in the second of these words is B.
The cache can then be found nearby at N44 58.CBD W72 23.1EA where C=A-2, D=B-2, E=A+D.
Container is a small lock n lock. Winter accessibility for this cache depends on depth of the snow for stage 2 and especially stage 3. Please be sure to re-hide the cache as you found it!
