I have stumbled upon that tutorial when trying to understand seasonal lot markers, so it has definately been useful. It should be kept around somewhere.
So far I've had limited use for the Boardwalk lot. I placed it in the Sunlit Tides world which I used for Sofia and Palash's honeymoon. The lot is cool enough, I mean, there's roller coasters in Sims 3. I have been sort of thinking about .. maybe.. using the roller coaster pieces to build something of my own on some other lot somewhere else, but I haven't gotten around to it. So far I don't think it would fit in anywhere.
I used to really enjoy playing The Roller Coaster Tycoon series back in the day, building theme parks was fun. ;) Though in real life, I'm actually terrified of roller coasters and would never ride one...
