When building the project I got this message:

MapLocation.cs(8,12): warning CS0642: Possible mistaken empty statement

And when I looked in Maplocation.cs, on line 7 I found a stray semicolon at the end of the line after the conditional expression.

That was causing the code block below it to be executed every time, regardless of the condition.

Good job. I tried to debug this for a couple of hours yesterday. Those damn semicolons are so easy to overlook, I didn't even consider the bug to be this simple.

The compiler messages can save you a lot of time, but you need to get into the habit of checking both above and below the line number they point to.
