It's shofar season, so if you haven't read my illustrated essay on exotic shofars and how they shed light on hilchos shofar, you might want to download it (free) at http://zootorah.com/essays. It has lots of unusual insights on everything from oliphaunts to jackalopes! If you are interested in purchasing any exotic shofars, I will have some for sale at the Biblical Natural History Experience next to Beit Shemesh; you will also be able to see my entire (and ever-growing) collection, which I'm pretty sure is the largest in the world, on display. During my recent globe-trotting, I acquired another artifact from the animal kingdom that makes the same sound as a shofar, but is not kosher to use as a shofar - can you guess what it is? Hint: There is a second-degree connection to the Mishkan.
