I see your point and I do consider myself very fortunate to not have to deal with a life-altering disability on a daily basis, but the problem is - "flexible" and "intelligent" just do not apply when it comes to most govt. regulation.
As for "flexible" and "intelligent" govt. regulation., I'll admit I chuckled when I typed that in. We'll be regrowing limbs long before that, I'll wager.
I'm not sure how to remedy the situation until then. It sucks that you have this extra burden just to use your own barn.
