So this is Valarnet. I was told this was the place to go if you wanted to be "in the know" outside of campus. I'm not sure what that flyer was all about - especially after looking at some of the other posts on here - but I figure asking some locals for some tried-and-true places to go sounds like the best thing to do for a girl still new to the city.
Personally, I've always felt that the bird's eye view is always the best way to get a lay of the land. Inside Orange County, the highest point is Santiago Peak - no relation - and I can tell you from first-hand experience that it's definitely worth the trip up. At the top there's really not much going on except a wide variety of communication towers, but if you turn back toward the coast... man...
What. A. View.
