well, at least you have an experienced partner with you if you ever considered just riding near the desert and then hitching the rest of the way. but free travel nowadays is hard to come by, so wear nice clothes and stick your thumb out. i've never been asked to pay for a ride but i have been given money and bus tickets from people that have picked me up. it might take awhile to get to NM, but thats the fun, the adventure. hope you enjoy your trip, i wish i could get the fuck out of madison.
