Photos from Lyndhurst Castle in Tarrytown, New York (Sleepy Hollow)
This castle in Tarrytown is really cool. It sits on a hilltop overlooking the Hudson River. The area is famous for the Headless Horseman of Sleepy Hollow.

Hi Chris, Thanks so much for all of expertise you share with us newbies to self-publishing. I’m considering publishing through Bookbaby and still need to know so much. Now I’m told I have to have a professional photo done for the back cover of my novel. I sure hope they can airbrush it. ha. Great site and again, thanks.
You’re welcome; I hope it helps. Good luck with your book. 🙂
Hello Chris ! I am a college student who just bought the ” Essential Calculus Skills Practice Workbook”, I want to practice calculus on my free time. Any recommendations for books that include random math problems or puzzles to solve for challenges or any of the sort ? Your work is remarkable and it is not taken for granted, that’s for sure !
I have a pyramid math puzzle book (and also a simpler 300 puzzles book). I like kakuro puzzles, which are sometimes called Cross Sums or Sum Totals. One of my favorite puzzles I came across reading Rudy Rucker’s book on the geometry of the fourth dimension; it involves hypercube patterns. As for random math problems, some math competition books have interesting problems, beginning with middle school for more accessible problems. For a challenge, check out Math Olympiad questions. (For algebra, I put together some of my favorite problems in 101 Involved Algebra Problems.)
