Hello David:

El Paso, Texas is the home of the largest Harley-Davidson dealership in
the United States!  A gift shop offering motorcycle memorabilia, leather
jackets, toy motorcycles, stickers, posters, art, limited edition items,
etc. would be a natural earned income idea for your museum.  Perhaps your
museum could also offer Friends of the museum memberships.  In return,
members would receive a newsletter, maybe a free home page on your site,
discounts on merchandise and other member goodies.  Don't forget to
create t-shirts, bumper stickers, and other stuff from your musum which
you can hawk at conferences, fairs, on your web site, cross-post on
motorcycle enthusiasts web sites, the list if endless.
