So, I'm just about at level 10 and heading to Boulder City. I finally got my lockpick to 50, and as much as I want to press forward to New Vegas, I can't help but think about all the doors and containers that I couldn't open.
Any notable locked loot in and around the early areas of the game? I'm trying to decide if I should backtrack for supplies or just press on.
Honestly, it seems like everything's just a big Giant U. I'd make note of locks you can't open and everytime you reach a new threshold, start walking the U all over again and get what you missed. Or if you don't keep track of things you couldn't unlock, just go back through everything.
