i was looking at my bike the other day... and i saw 2 holes... one on each side that appear to be nothing, but i was wondering if anyone else had them, or knew what they went to?
about an inch below the seat on the subframe.

zoomed out a little bit so you know where i'm talking about.

sorry the pictures are a little bad, but it's night time and i wanted to get them while i was thinking about it.
