Hi I'm going from 20 to ~100 in my third winter of tapping ever (moved from the desert) so I'm right in line with your statistic.

The local sugar shack owner said he will be happy to take extra sap and trade for syrup (probably at a rate that'll still make him some money). I believe he does that with several local tappers.

You may want to talk to a local sugar shack and do some good old fashioned bartering.
