Creating the feeling of space in Second Life

Lately content creators have been building sims with huge vistas that actually make it possible to feel like you are enjoying large open spaces.  

Today I checked out Landscapes Unlimited and was pleasantly surprised by what I saw and more to the point what I felt.

I came across this group of friends looking out over the valley below and I really did have the sense of immersion in an outdoor space that Second Life has been lacking for me.  I could almost feel the breeze on my face.
