New domain, new host, new CMS, welcome.

If some of this material looks familiar it may be because I am moving the content from my previous non-descript domain,, to an equally non-descript domain,

This year I am planning on making an effort to document more of my projects that I think will be of use to others.  This is the only useful way to payback other that post the important details of their projects that help me so much.

Thanks for stopping by.

Bicycle Bus

I was doing some research on bus conversions and came across the following site:

This is the history of the Bicycle Bus or more specifically the recent history of Toma and Ellie Holme. Interesting in a number of ways, but definitely insight into a unique couple who have spent the better part of their lives on the road on the west coast.
