SPOTLIGHTJUNEAU EMPIRE It's not too often that you get to see a live alligator in Alaska. Nature enthusiasts of all ages will get that chance on Sunday, Oct. 19, when nationally known naturalist Scott Shupe presents a 45-minute program at the Douglas library beginning at 3 p.m. titled "The World of Reptiles." Shupe has spent the last couple of months crisscrossing Alaska, visiting schools and libraries with a motley group of reptiles that will get to spend several days in the capital city.
