Ross; keep your chin up. I've been following this with great anticipation as you were actually pre-scouting for some of the areas that I will be going to in another couple of weeks. You did have a lot on you plate, and I think w your next venture, you will have this all ironed out; traffic/tires etc.
I've ridden with you and you are a good and very cautious rider. The car tire thing sounds like a thorn more than anything. If you don't feel comfortable it will and can ruin the adventure.
I commend you for the huge effort, and dealing with us crazy Amerks during our busiest of holiday weekends. You got nothing to be ashamed of and it happens to all of us.
I truly feel for you and at the same time look up to you as even taking this venture on!... and all by yourself!! cudos.
When I posted my upcoming 8500 mi itinerary here, I had a lot of great input/tips, as I know you did also. But, you just never know until you are out in the vast and have these curve-balls thrown at you. As you know, I went with each days legs planned with hotel/motels booked on each end. I knew being the end of July, that nothing sucks more than a tired rider being told that "I heard that the next town may have a room or two" only to get there and it's already gone. So I'm going pre-planned lodging, the main downfall is that if it is an all-day rain, we still have to do it; no days off!
Keep us up to date, and I hope your return trip is MUCH LESS stressed!!!
We'll tip another beer together, and, soon again I hope!
