I'm new to the site. I will be traveling with my 15 yr old son, next June 2006 from Spencerport, NY to Estes Park CO. We have our agenda planned to Colorado. We would like to take a southern route to visit my sister in Raleigh NC via Route 40. I'm just unsure of any "must see" attractions that would interest us via Route 40....Amarillo, Oklahoma, Arkansas....etc. Any suggestions not far off 40 would be appreciated. We have a full week to enjoy from Colorado to NC. Thanks!
