St. Louis has been created in Second Life. Now you can ride a steamboat down the Mississippi or visit the Gateway Arch from the comfort of your own home. While visiting the St. Louis virtual sim in Second Life you can get a free avatar St. Louis t-shirt and see the sitess such as the Old Courthouse and Cathedral. Other major virtual sims of a similar nature include London, Galeveston, and Washington.

The St. Louis Convention & Visitors Commission is very pleased about this new form of advertising and hopes people will visit in real life. Designing Digitally created the virtual St. Louis sim.

On a related note I found a video of the Spirit of St. Louis plane taking off:

Maybe you could take an airplane virtual tour of the virtual St. Louis.
