I've been working on making a 25x25 crossword off and on since the last one I did wasn't very good. I need a second pair of eyes to make sure I haven't used a word twice, or make any misspellings, or put in a word that doesn't exist. By the way, "NGC" stands for National Geographic Channel. Thank goodness the good folks at National Geographic made a channel, or else making this puzzle would have been even harder. So here it is for your perusal.
