So, here's what happened.
I was originally supposed to go to this club to see a DJ I'm a big fan of with a couple of friends who are also big fans. Buy my ticket beforehand and everything.
The show was 18+ at the Loft, so no problem. I mean, I went out and bought a new outfit and everything for this night. (It's on Nov. 10th, btw)
Anyway, yesterday I hear that they moved the venue for some unknown reason, to Foundation, which is a strictly 21+ bar. So I call, all pissed off. "I already paid, why did you guys move it, this sucks, fuck you" was the extent of the conversation.
My friends are all over 21 except for one, and she said she doesn't care anymore, and she's not going. But I REALLY and I mean REALLY was looking forward to this. I am insanely pissed off that they changed the age limit on the show.
So now I'm thinking, can I get in some other way? I've never tried to get into a 21+ club before so I'm not too informed about how strict they are about checking IDs and stuff. 18+ they don't seem to care very much at all. I'm assuming 21+ the bouncers are more thorough about carding.
I don't know where to get a fake ID and I don't have any friends over 21 who look enough like me and would be willing to lend me their ID. Is there any other way to get in or am I totally fucked?

Help is appreciated.
EDIT: I need to take a shower and do laundry so it'll be a while before I can reply.
