There is a lot of maple trees in our area. All kinds of trees for that matter but I have never heard of anyone tapping them. I think it might be a good project some year...
I don't know how cold it gets there but it might be that no one taps them because it isn't cold enough.
Selling raw sap? Wow I would have a hard time selling that I imagine. I could probably sell finished syrup but nowhere near enough to pay my taxes! Lol NH taxes are bad though.
Wow, good score on the stroller. My oldest daughter was croupy when she was a baby and the only time I could get her to sleep was an afternoon stroll outside then she would sleep for a few short hours when we got home. Also, the only time I could sleep. I want so much to have rhubarb. It's not really a crop people grow here but I love it. Rarely even see it in the stores and when you do it's not in good shape.
You are able to dehydrate frozen vegetables. The only thing is you end up with a syrupy film on the bottom of your dehydrator. I like to do this because you are able to take your time when you have so much surplus it would spoil otherwise. I am already getting ready to slice and freeze bananas to dehydrate later (if the kiddos don't eat them up first).
