Mine don't get stuck. Maybe coz i'm running the double pack. i could try and take a pic with my digital camera for you but it won't be very good quality from the t.v screen.
No a news station with crazy news like ''a hoard of flesh eating monkeys have escaped from the zoo and are currently chewing there way through downtown''. that would be funny.
Its a good idea but i see one problem. At the beginning of the game people could swim to the second island and that would cause problems. And an invisable wall would take away the effect of gta.
