I'm pretty sure it was Fox River, when it zooms out is shows the same layout and rooftops we saw in Season 1, pretty sure of it anyway. I guess your right, Sara still isn't free and neither is Linc now seeing as he helped her escape, same goes for Mahone and Sucre if they get the evidence. Although I suppose if they were going south of the border the chance of them been found are pretty low considering Bellick didn't find Surce that easily in season 2. I agree with you it seemed abit rushed, I was looking forward to the entire elaborate and clever escape plan that we saw from Michael in season one, especially since the prison was "air tight". Would have been more thrilling without the flash forward from the series finalie though.I don't think it did when they did the day - night background thing, and if it was Fox River I reckon they would have made more of a deal about showing it. Also, the way T-bagh was acting it was as though they had suddenly thrown him into the more secure area of the prison he was in rather than transporting him. I dunno though. A very sad ending but I liked it.
