I'm almost certain that in the beginning the three Traxx (NYC, DC and Denver) were owned by the same people and it was a chain, but later the original owners sold off the franchise one by one.
Arguably Traxx DC could have been the best of the three. I only went there a few times in the early -mid 90s but was impressed with how it blended the music of the NYC version with the indoor/outdoor ambiance of the Denver version, which also featured a large outdoor patio and sandpit.
But the NYC Traxx remained my fave, back in the day when Crack was King - and those vogueing wars - ruthless battles to the death! I remember they often spilled outside after the club closed and were carried on further at the nearby piers until the wee hours of the dawn.
