The KATY trail is not too far from you and would be a good week long trip with no traffic and lots of small towns to tweak your gear. I am planning on the Southern Tier in the next few years. I turn 50 in Feb. so at min 5 year to retirement. Look at the Kona Sutra bike (regular not LTD). Lewis and Clark sells them. IMO its the best looking touring set up. I will own one within a year. I currently have a highly modified Specialized Sirrus that works great as a commuter and touring. I want to do a week or two tour in the spring. I live in Russellville. PM if you would like to try a small one before you do your epic adventure.
