How can I check my location in Finder?

I like to include checks at the beginning of most macros to ensure I'm only working in certain documents or folders. By checking the frontmost app, window, title, etc., I can get most of this done. This is what I'm currently using for checking the path and ensuring I'm in the right folder. Is there a better way?

You could use the FinderInsertionLocation token to check the parent folder is reasonable.
