There is really not a place in this game to Base Jump from. I miss that.
In my real life I have Vertigo (mild fear of heights) and I get a giddy thrill from jumping off of high places in games like this.
So, give us a Lover's Leap. Heck, put a Diving Board there so we can walk out and do a nice Half or Full Gainer as we dive.
Note, there are diving boards in the game, they have no springiness or physics attached to them, but all the same, it would be perfect for this.
