I just got this comment on my older post Million Dollar Ideas #4: Nails on the Run.
Funny you posted this idea, because my mom and I started a mobile nail salon that travels to businesses, parties, special events, etc. We are called a Nails on the Run and located in Corona, California. We started our business in November 2007, but has been in the planning for a year prior to this - and is so far a growing success! Our website should be out this week: www.nailsontherun.com.
Nails on the Run
I'm not sure which makes me happier, that someone else also had the idea, or that they even used the same name I came up with. In any case, I sure wish I lived in California right now. If you do happen to live there, go check it out.
Heck, sounds like a great road trip destination!
