In the woods I'm able to look at the whole tree starting with the bark because it's easier to see up close. This is usually all I need. If I can't decide from the bark then I go to the branches. Many times the bark has a different appearance even on a single tree (as anyone should know). A photo of one section of tree does not give a true 3-d perspective and may confirm nothing. The opposite twigs (as I've said from the beginning) is the tell regardless of the look of the bark. Ryanscloz indicated that he knew about opposite branches and presented the photos as possible maples.
On the boiling down of 2 cups of sap to a tablespoon - I say there is no way it can be done without a serious melt-down, particularly someone who has never boiled. And, it's not necessary. So don't go scolding me about misleading anyone.
