Heroes Among Us was featured at DEC. It is a very nice place for sound and visual events. A big shout out to Waldens for the videos.

I had never been to this venue until I recently performed there with the Metropolitan Chorale. The venue was easy to find and accessible, and it seemed intimate yet accommodating, especially when we ended up with a larger than expected crowd. While it was not like singing in a cathedral, I was also pleased with the acoustics for a performance of this type.

Diamond Event Center is a beautiful building with friendly people. It houses everything you could need as you age. From fine dining to an Olympic sized pool shallow enough for water aerobics. I don't want to live there when I'm older, I want to live there now!
