Springfield Help

[Magus Zeal]

I'm on mission 8, Springfield, and I've hit a bit of a snag. I've gone through the main road of town, clearing out each building and around them (so I don't think there's any Raiders left). Problem is, there's a gate to the entrance of that park in front of the town hall, and I cannot find a way to open it -- perhaps I'm just missing something. I've checked out 3 FAQs from GameFAQs and only one mentions Springfield in passing, none of them having any information on the mission itself. Anyone have any advice?
Edit: False alarm, folks. Looks like FT's wonderful pathfinding strikes again.

Also, while this is not related to the main question, how good are Trauma Packs? I've heard they're excellent to prevent overdosing on drugs, but anything else?
