The Sounders continue to break boundaries in terms of attendances in MLS and McBride, an ex-Fulham, Chicago Fire and Columbus Crew striker, says it is a very special thing for the league to see this occur.
"To see 64,000 people, from the beginning, doing that clap thing, this was just an amazing sight," McBride told the Seattle Times.
"I mean, unless we were playing the Mexican national team, crowds like this were unheard of when we played."
The match marked the final Sounders home game for veteran goalkeeper Kasey Keller and McBride was so happy for his former US teammate.
"The whole experience was great. I'm so happy for Kasey," McBride added. "To have these 64,000 fans for a regular-season MLS game is very special.
"Can you look at what happened tonight and what's happening here and say, 'How can we do this in other cities?' Sure. It can be done."
