I'm mapping a tour I'll be taking this summer from Florida to California (creating routes on mapmyride.com to upload to a Garmin Edge) and wanted some help on biking interstates. Specifically, I-10 from Las Cruces, NM through Arizona and through some parts of California. I'd much prefer back roads but I haven't had any luck finding sure-fire routes that will get me from Albuquerque to Tucson. Can you even bike on interstates or I-10? Any advice or personal experiences?
