I'm thinking a dedicated four roller machine is in order after checking out your AZ abandoned RR links. Throw a couple of them in the back of the ruck and head north to the pines.Had a thought. What if the front MB wheel is suspended between two rail wheels, spaced far enough apart so that the bars could not be turned? Rear wheel in direct contact with the rail would/could only follow. Would take some getting used to and would be high when taking off on track alone but could be done easily from where a road crosses.
If it could work, could be mounted so it swung up and out of the way for road use.
What do you guys think?
I'd like a nice bucket seat and a cooler for lunch and beverages.
I'm completely serious.
