Do I have enough time to mostly avoid interstates?
I'm heading out in late July and have 2 to 3 weeks to wander. My rough plan is to hit the interstates to Little Rock, AK (I've been all over the southeast on many occasions). After Little Rock I'm aiming for Routes over Interstates. It'll end up looking like a loop jutting out from Florida to Yellowstone then down into Roswell,NM and back again. My target stops, tentatively, are - Little Rock,AK - Oklahoma City,OK - Wichita,KS - Garden City,KS - North Platte,NE - Mount Rushmore - Yellowstone - Rock Springs,WY - Aspen,CO - Santa Fe,NM - Roswell,NM - Amarillo,TX (for the 72oz. steak challenge at The Big Texan)- Austin,TX - Houston,TX and back home again via I-10.
I don't want to rush, but if I need to I can switch to Interstates. Is this do-able, or totally insane?
