I think they probably did take the weapons. There was a big pile of stuff covered with a tarp in the back of the pickup. I figured it was either supplies or weapons.Didn't quite get why Rick didn't scoop up all those weapons the Governor and remaining henchmen left behind - unless we're to assume he did at some point - and why everyone didn't opt to relocate to Woodbury, which has to be more comfortable than the prison.
I wish the Governor hadn't killed all the young (fighting age) men. Chris Hardwick joked on TD last night that the youngest person coming off that bus was like eleventy one years old. Will the larger numbers end up being more of a drain on their resources without any benefit to their defense?
I think they opted for the prison because, once they rebuild the fences and get the walkers out - which they can do with more people to help - it's more secure than Woodbury. Plus, if the Governor comes back, he knows Woodbury really well so he could launch a surprise attack pretty easily. Not so much with the prison.
