I am planning to use the Adventure Cycling map set tour from San Diego to Austin TX later this spring.
San Diego to Tempe Tempe to El Paso El Paso to Del Rio Del Rio to Austin
I would like to contact anyone who has ridden all or part of this route within the last year or so. I don't have any specific questions, but anticipate there may be some as I get closer to leaving.
Specifically interested in conditions, traffic, services - etc.
I don't meet your description. However, I did cycle the route in 2001 and posted my trip report and descriptions here: http://www.mvermeulen.com/oneyear/usa.htm It has some of the (dated) perceptions of services, traffic, etc.
