Nice mod, nice to see you still working on it. Just a few problems I had it seemed most of the missions was drive here, then drive here, on one of the missions you have to follow a van to the power plant then drive home, then the next mission you have to drive to the power plant again. I would say mix it up abit and try to make the most of the map, I dunno maybe homer could collect something off the top of the gold-ish bridge. I think the garbage truck needs editing, when going to hit it I would sometime go underneath and also the rubber-banding need tweeking (if you can tweek it). Im currently on the mission where I have to pick the kids up from school and I'm stuggleing to finish it, the driving from place to place is wearing thin and I keep running out of time on the way home so maybe add some more time maybe, ill post again when I complete it.
Apart from all that and I still think you've done a good job and look forward to seeing what else you add. :D
