Spring and fall up north, I know because I've lived in several northern states, can stay wintry but are terrific seasons to see the Stockyards. A visit to the website (http://www.fwssr.com/) lists events, recurring events, shopping, dining, lodging and dining.
Booking a room at one of the hotels provides a great opportunity to poke around the shops; schedule a trip on the Tarantula Steam Train and ride to Grapevine and back; and you won't miss the daily long-horn cattle drive at 4 p.m.
Dining is a treat, from Riscky's Barbecue to the Lonesome Dove to the Cattlemen's Steakhouse. No one should miss Billy Bob's Texas Bar B Q, famous for the star western bands who perform on a regular basis.
Anyone living in northern states should consider the Fort Worth Stockyards. Yeee! Haaa!
