I proposed at Cedar Point on the boardwalk. MF lift hill was my first choice, but it was broke down. So, we walked around the park and out to the boardwalk. We were standing there looking out into the lake and I asked her, "If I bought you a ring, what size would I get?" She answered and I grabbed her hand and slid the ring on her finger and asked "Is that close?" She said "yeah" and stood there and looked at me, then looked down at the ring, then back and forth. I said "Will ya?" She finally said yes once she realized what I was doing.
If I would propose at another park, It would be at Universal when Jaws popped out of the water.
