One tip and tidbit about Pointy Mountain:

It gives you 1 extra helipad in the form of "Mountain Helipad".

Thus, at museum level 75, you can have a total of 6 helipads instead of the usual 5.

It may not matter to some, but I usually allocate space for the helipad even before I can buy all of them. This "extra" helipad gives me a big dilemma now at museum level 75 because I don't have any outdoor space left for it. Sigh...
