I agree with Lee. 7.5" is way too short. Trees are more likely to be 70ft to 100ft tall. 30ft is an adolescent tree, maybe.
Interesting that people will invest $1000's of dollars for engines and railcars that sit in boxes under their layout, never to see the light of day. But wince at buyimg trees that will be on display, functioning, and noticeable 100% of the time! (But a grand a dozen is pretty pricey, I admit)
