[size=2][/size][b][/b][i][/i]there are only 2 gaps impossible to find here
'extra credit transfer' and 'show and tell'
where are they?
the others are easy to find provided one looks carefully
'it's sidneytime' is a transfer. look carefully amongst the vert ramps. 'bank shot' is the grind around the ledges in front of a building which has a oval grinding patch on top of it and which is connected by a wire (thats the only way u can enter that area).
'clear the perimeter' is the grind around the park (you gotta hop on to the walls surrounding the park and grind the whole thing)
'pool boy' grind the whole pool next to the north-eastern building.
'xsportsmastah' do the 'VV university' gap and go on hop on to the next ledge and grind it.

That's all that I've got so far
The others which I have not explained have to be found by you since they are not easy to explain here

With reference to my previous post,
I finally found out where the 'extra credit transfer' gap was.
In CA College there is only one car around. go to building next to it and start grinding the ledge above it through a wall ride. Then jump of and start grinding the railing present below and voila you should have the gap in front of you. If it doesn't work the first time, just try it again till you get it.
I'm still working on the 'Show and tell' gap. Please notify me if you find the gap or know where it is.
