This spring break, mid-april, me and a few friends want to go on a road trip. From San Diego to whever we can get to (and bakc to SD). We would like to hit the South Western and maybe Southern US (at least AZ and NM, maybe TX, CO, NV, UT, LA, etc). We'll be on the road about 12 days.

SO, what are some interesting places we should hit, or at least think about. We've already got some ideas, but your input would help.

Also, about how far do you think we could get (and back) in about 12 days? Thanks.

Matt
