Website Theme Change

On October 9, 2025 I changed this site's theme to what I feel is a much better design than previous themes. Some pages will not be affected by this design change, but other pages that I changed and new pages I added in the last several days need to have some of their photos re-sized so they will display properly with the new theme design. Thank you for your patience while I make these changes over the next several days. -- Ray Merriam
