A man by the name of Michael Maresco of the Ron Paul Riders submitted this video that he shot of Dr. Paul. The goal of the "Ron Paul Riders", as listed on their site that I linked above, is stated below:
"A two-month-long journey from California to Washington DC on bicycles? Yes, and in every town along the way, the Ron Paul message of freedom, prosperity and peace will be the emphasis".
On his way to D.C., Maresco was able to meet up in Texas with Ron Paul, and they had a good 10-minute bike ride together. After the bike ride, Dr. Paul submitted this message to Ron Paul Nation. Thanks to RonPaulHawaii of the Ron Paul Forums for the transcript.
