Luck luck luck <--- wished your way!
I think you are awesome for doing this! Denise Goldberg (I think you can look her up on crazyguyonabike) has done lots of solo touring and actually lived to tell the tale.
I don't know that I'd want to solo tour, but not so much from a fear factor (I love solo riding!) but just from an "I want to share every bit of this with someone special") standpoint.
I totally get what you are saying, though. My DH and I are moving to Belize later this year, and we get the same reactions. It's crazy how scared people are of life! I got this reaction when talking to a couple about Belize at a rest stop on a ride this weekend. I finally said "If I were scared of life, I wouldn't be riding on the road". They took pause, since they were also riding on the road!
Good luck! I will follow your blog. You rock!
