Since I should be doing homework, here's a crossword puzzle: Frontiers.
As usual, I haven't done extensive proofreading: that's what my loyal readers are for. If you find anything that is or might be wrong, please tell me.
You probably thought this blog was dead. So, have a crossword! This is my first crossword that completely follows the typical American layout conventions.
As usual, it's late at night and there could be a typo. Please send me bug reports. EDIT: Due to popular demand, I have devised a way to render this crossword onto a single page.
