Well this obviously blows away the Texas Star as the tallest Ferris wheel in NA.
From Wikipedia:
"Texas Star is the tallest Ferris wheel in North America.[1][4] It is located at Fair Park in Dallas, Texas, and operates during the annual State Fair of Texas,[2] where it is the most popular ride.[4]
The structure has an overall height of 212 feet (64.6 m) and can carry up to 264 passengers in its 44 gondolas.[5]"
From About.com:
"The Texas Star is one of the most popular rides at the State Fair of Texas. But don’t be discouraged when you see the line form because it moves fairly quickly. The ride lasts about twelve minutes. I was a little nervous during my first ride because I was up so high, but it was an incredible feeling."
