The walk, again.

Once again I have been thinking, no dreaming, of "the walk". A walk-about as it is know in Aussie land. I mapped my route out of Texas to Northern New Mexico were I will be briefly before hitting Colorado and the Rocky Mountain trail to Canada. The Texas to N.M. is 157.5 miles or there about. If I can log 20 miles per day, that is only 2 miles per hour at 10 hours a day, I can be to my first destination in N.M. in about 8 days of travel. Add for unforeseen events and it could be 10 days or so. If I calculate for Bruno marking like he does then we will arrive in New Mexico in just under 8 YEARS! Just kidding Big B. We both pee every few steps, must be a dog thing. Anyway, 2 miles an hour is very doable for us as we average 3 to 4 on even terrain. Sure the days will be long, but interesting and of course there will be breaks for rest, grub, and just to look at things. The trail over the Rockies, if that is the path we travel, will take much longer due to the terrain and elevation but it is something I would love to do!
Some of the gear needed is pricey, emergency radio for weather reports, solar charging panel, and some camping gear to name a few things. Those can be purchased a little at a time due to lack of funding and e-bay is a wonderful thing for finding these things at reasonable rates. The thing I run into is lugging supplies. For myself it is no big issue, but for my dog owner, Bruno, it may just be an issue. I would need space for his food and they do not sell his brand of food in anything smaller than 30 pound bags. That is a lot of space! No way will that fit in my pack with all the other needed gear. I have considered a pull cart and this sounds like a keen idea....until the mountains. Then the trail is uneven at best and not exactly smooth. Tugging on a cart at that altitude and terrain might take a while. So now I must find a new idea. I could sure use some help brainstorming this problem. Any ideas that any of you have would be a great help....possibly. I know some of you and answers like storing the food in your bum may pop up. I have already thought of this and concluded that the food will NOT fit, thank you very much! It may also turn out that I must adjust our route to a more subdued trail avoiding the mountain paths for roads.
In any event I need to remove this chair from my duff and get B and I out the door for our morning hike. Can't get ready for the trip by eating chocolate and playing on this thing....DAMN!
