I am finding the first year pretty different then I expected also. I figured that once it warmed up the stupid trees would start dripping. Turns out my idea of warm and theirs is a bit different. I get lots of exersice so far also as its a half mile down the the end and back and I traveled it 5 times today. Out of all that I got 4 liters of sap and a sore back. I am looking foreward to the next day so far still.
Jax try and mark all your trees this summer so that you can find them easy. I did mine with red surveyers tape and then it was a matter of just wadeing thru snow and tapping them.
