Route 66 wiki If you follow the old route up to Las Vegas, NM and Santa Fe then down to Los Lunas instead of staying on I-40 to Albuquerque, there are plenty of sights and places to see.
I would recommend that you do NOT try to drive Central Ave (66) in Albuquerque. The few Old 66 sights to see are overshadowed by the homeless and hooker sights. Use business routes through Tucumcarri, Santa Rosa, Grants and Gallup, NM to see some 50's era business establishments that are still in business. Mostly closed store fronts though. Have a Blakes green chili Lot-a-Burger while in NM and find a restaurant serving Sopapillas with the meal. I recommend Garcia's in Albuquerque at Wyoming and Indian School for Huevos Rancheros. There are lots of other places but Garcia's is fairly close to I-40 and is one of the best.
