I wish all borders could be like this

I have a tendency to get lost in Wikipedia, bouncing from page to page chasing curiosities. Last night, I learned this about Liechtenstein:

During the 1980s the Swiss army fired off shells during an exercise and mistakenly burned a patch of forest inside Liechtenstein. The incident was said to be resolved “over a case of white wine”.

In March 2007, a 170-person Swiss infantry unit became lost during a training exercise and inadvertently crossed 1.5 km (0.9 miles) into Liechtenstein. The accidental invasion ended when the unit realized their mistake and turned back. The Swiss army later informed Liechtenstein of the incursion and offered official apologies.

Yes, really.
