My Metropolis seems to be shrinking...... but that might be because I carry my Timbuk2 XL to school and save the Chrome for everywhere else. I just got too sick of asshats going for the seatbelt buckle between classes.
Like, seriously. The Metropolis was a freakin cave when I first got it (upgrade from the now-defunct Auclair Cocotte-clone). Now I seem to run out of space in it really, really fast.
Maybe getting that XL is really messing with my standards.
