Yeah...that is sad. I've never seen that one down in Manitou, but I'll have to check it out before it goes (let's hope it doesn't)...
One of my favorite arcades (not too far away) has always been the Boulder Boardwalk on the Hill at CU. They seemed to have a great mix of old and new, and an atmosphere that just made it fun to go there...
They are a dying breed, for sure...
