Am I crazy? I must be, because I’m doing three book signings this weekend. But that’s good for you and any other Christmas shopper who’s going crazy trying to find the perfect gift for that certain St. Louis history lover. Today, Saturday, I’ll sign from 11 a.m. to 3 p.m. at STL-Style/Stylehouse, 3159 Cherokee Street and from 5 p.m. to 9 p.m. at Half Price Books, 630 McKnight Road in University City. Then on Sunday you’ll find me from 2 p.m. to 6 p.m. at the Tower Grove Farmers Market’s outdoor Boulevard Holiday Market, 1 The Boulevard, Richmond Heights, off Galleria Parkway across Brentwood Boulevard from The Galleria. If you think that’s crazy, I have four signings next weekend.
