WOW, I remember those buckets! We rode them the first[and only] time during our first visit to WDW when the Castle was a hideous cake! [which I thought ALWAYS looked like that.]
I loved the Skyway and rode it whenever we could! It gave such a great view over much of MK. Luckily we got to see the castle without icing several times before 1997! So I was very happy to see the Skyliner added to WDW.
