This worked out like a charm!! I parked in the adjacent parking lot, and my fiance and I walked towards the water tower since she said she's never been to it. We were supposed to meet some friends for dinner, and I said it would be an easy short cut to go through there. Anyway, we stopped in the middle, with the water falling all around us, and started with a kiss. I told her to look up at the water falling, and at that moment, I dropped to one knee. Once she looked down at me proposing, she abolutely flipped! Be prepared for waterworks, and not just from the water wall!!!
Pros: great setting
Cons: you'll get some drizzle on you
