To be truthful, most of us couldn't distinguish one DC from any other.
The only way I can remember different DCs is when they change from one venue to another.
They were in one place for over a decade, when I was kid into my teens (I remember those because of the discovery of girls and scoping them out during the sessions and the breaks. Even though these happened so long ago, I remember more from them from a social standpoint than any since).
Then they moved to another place for a few years (I remember those because some of us would rent rooms together and end up partying each night. Actually had fun at those. Slept during the sessions).
Then they moved back to the original one for several years (Don't remember them too much...getting older, bored).
Then back to the second one for two or three years (Now I'm married...barely remember being there).
Then to a third one, where it's been for close to a decade now (even though these are the latest ones, I remember next to nothing about them except the last few I went to I had already checked out mentally).
