I checked the 100% completion list for VCS PSP...
there was either an omission or we got 1 small new side mission for the PS2 version.
...And feel free to correct me if I'm wrong.
It is very similar to the bus mission at the studio on Prawn Island(Crash)...
do so much damage in a certain amount of time.I don't remeber doing it on PSP.
I just jumped in and did it and didn't bother with the name.
It is a tractor trailer rig(no trailer) parked in the area of the Forklift near(West of) the vehicle collection spot.
It is near all the containers around the bend.Good luck!
I have completed pretty much everything but what I find somewhat boring...taxi,ambulance,balloons.
I'm gonna leave 1 slot for these plus Rampages and Jumps,and save the last slot for Empire Building.
Petty much what I did on PSP.
>>>edit...also, there's another PCJ playground bike at the back corner of your first save house with a garage!
