Come to think of it, my grandpap had the first neck bag I saw in use back in the mid-1950's.
He was a heavy equipment operator, and he kept losing his bag of Bull Durham from his pockets. Money was dear, and he hated the waste even more than going all day without one of his "taylor mades."
He tied an old shoe string to the draw string on the bag, put the rolling papers in the bag with the tobacco, then hung it over his neck for the day. Another side of that, he didn't spill the bag or drop it while rolling cigs on a bouncing machine.
I got to ride on a road grader with him several times, and watched the show every time he rolled his own. Only man I ever saw who could do it one-handed and without gummed papers.
I was fascinated, but Momma would have no part of a 5-year old smoking. So we compromised and I used his cast off Bull Durham sacks to carry BB's. On a shoestring around my neck, of course.
Soooo, my conclusion is neck bags are practical for things you want handy, but tied down.
Oh yeah, I roll my own to this day. And I've tried for years to do it one handed. Must not have picked up that particular gene from the gene pool, because my efforts are most certainly a waste of good tobacco!!!!! :rotf:
