I came across Leyda, Burrus and Metz Monument Company in Burlington, Iowa's page and was "WOWED". The company was formed in 1892, making it one of the oldest monument companies in the Midwest. Ron Dixon is highlighted on the site and his work is fabulous.
If you want your life "etched in stone" he's the guy : )
Check out some of his work. I've put a few pictures up to show you!
P.S. You can have him start working on your masterpiece while you are still breathing : )
