Is this frame safe to ride?

I am Crazy mate, but i'm not Crazy enough to ride a semi-broken frame!
For the love of God, please do not ride this frame, if it breaks you are going to have a really nasty crash, and probably lose half your face to the tarmac, it is just not worth the risk!
Also sticking a brake on would be a sensible idea, at least until you can control the bike properly.

The guy at the shop I was at today to sort out my rear hub told me that it most probably wasn't too dangerous to ride, at least for a short period of time..but I'm still sceptical, I might just take your advice and bin it at once..

I already have a brake at home, so as soon as I get the new frame I'll mount it. But now that I know how to skid properly it's not a big problem to ride brakeless (yeah, until this happens that is)..
I was lucky enough to not get ANY marks on myself though, but I think it's once in a lifetime kind of luck..=P
