I'll reply here, so your efforts weren't wasted.
No, I was never at Toledo Sports Arena. But I doubt you ever carried a tape measure with you while you were there, so all either of us have to go on are anecdotal data. In your defense, there's a Wiki page that reports the TSA was 33-2/3 feet tall (I presume you didn't write it or you would've cited that number). From exterior photos available, I could believe that height for the ground base of the exterior concrete structure to its top. Add to that the arched roof structure, and I'd estimate total exterior building height as a minimum of 50 feet (still a pretty dang short structure, for sure). Moving inside, I see evidence of a ground-level concourse with direct access to the top row of bowl seating. So presuming standard 48-inch tall dashes topped by the 3-foot glass height reported by CrazyEddie (proportions look about right), I gauged the height above the glass up to the last rows as approx. another 3 times the board/glass combo. That makes 28 feet from ice level to concourse level. 28 feet + 50 feet > 40 feet. Anal enough for you?
