Wow, that is a tempting, tough call...
Maybe if our next president manages to straighten out our health care system, re-balance our budget and find a fix for social security, then it would certainly have been worth it to wave your hand at the big corporation and go it your own way... but, without these things, there is certainly a greater security in staying with the devil you know..
IT would seem like a dream like opportunity, though. Someone once told me when I was thinking of taking up the music business professionally, that once they turned their passion into their daily business, it lost all its lustre. I suppose that you can take consolation in that motorcycles and puttering on them will stay more interesting for you much longer this way, than if you had a bunch of weirdos like us lined up at your front door every Monday morning, wanting their beloved 30 year old antique motorcycle running perfectly again !
