My neighbour has a very large tree on his property which I've often admired from our house. It's difficult to miss because it's the tallest thing around. I'm no expert at judging heights but it looks to me as tall as a 10 storey building, so I'm guessing 100' (30m). Now, that's not nearly as tall as a sequoia or a redwood, but in these parts it's got bragging rights. Today I trudged through all the snow we got yesterday, crossed the fence to my neighbour's, and paid it a visit. I hope the photo conveys some sense of its size and height.
