I have no local experience, so what I say below may not be relevant here.
In Southern California, I have done work on several local "mountains". They each have multiple shacks & towers. Each shack has racks in it that are leased/rented out. Each tower has a bunch of antennas on it, owned by a bunch of different organizations.
A lot of it is high-power stuff. Pretty dangerous to be too close (walking around on the ground should be safe).
If there's a ham repeater up there, a HT would be very useful. Even if the repeater isn't linked, you could use it for simplex and get *big* range.
