I just came thru your path this last Tuesday, the other way and arrived home Wednesday afternoon after dodging thunderstorms thru out most of Texas that day. I spend Tuesday nite in Brownsfield, Tx and woke up to rain.
I may have been the Vstorm you saw loaded out. I know I saw several Beemer GS's ( which was the top bike I saw on the road other than Harley's and other crusier types ).
Have a great trip, and, get into the Rockies, they're beautiful. You're just skimming them on I 25. ;-)..
