I don't want to ruin the movie for you but I have to tell you that there are no trolls in Troll 2, but there are Goblins and that might help you figure out the name of the town in the movie:
There was some time in between the panel and the screening of the movie so we met up with some other friends to have dinner and then Tasha showed us around Morgan. Look how amazing this place is:
It also turns out that there was a girl there that I know from college and she is married to the guy who played the part of the son - Joshua in the movie. There is actually a scene where he pees on the food his family is about to eat so that they don't turn into Goblin food. Don't worry they don't show anything graphic - it's all inferred. This guy is now making a documentary about this movie called "The Best Worst Movie"
