Railways would have been around during Warehouse 12, though. Cars might not have become commonplace until Warehouse 13, but they would have still been around. Even bikes were around - I think possibly as early as Warehouse 11, maybe 12 - which would have made travel easier.

I doubt the Warehouse is under that much danger each year, because that implies that a large number of people know about the Warehouse, the most secretive thing ever. I mean, even the U.S. Government isn't aware of what goes on there - At least, as far as we know of. We might have seen that play out with a full Season 5, but alas: no dice. And if the head government was fully aware of what the Warehouse did, they would definitely never let it move out - no matter how weak that country became.

I think presently, the Warehouse is in more danger from outside threats more than before, only because of the rumormill called the internet (Fargo confirmed that there are rumors of its existence on the internet). However, I highly doubt its multiple threats every year, or else you'd have much more security. It'd become an "Area 51" situation, where you approach a fence and many guards come out to meet you. Or even if they wanted a more stealthy approach, they would still have a massive security force to prevent snoopers.

I figure that there might be more threats as a whole in the past, mostly because the empires of the time would want control of the Warehouse. I think there are gaps in terms of how often the Warehouse is in danger. The show focused on a heavier period, if you will; although when you think about the villains, three were former Warehouse employees (13, 12, and 9 respectively), one was an alternate reality (which likely would have been linked to the Senator's visit - again, hypothetically). Only one of the villains was truly an outside danger.
