Reading this, I think I may be in a 'professional' band. Hadn't really thought about it before.
And just for the record, I have a day job, but I'm self employed so can (almost) pick and choose when I work. We also schlepp miles around the country but its 90% done at weekends.
And a 2hour drive? But a mere hop
I think, even though I agree with all the sensible replies on here, if you don't give this a go, you will always be thinking 'what if....' Life is for living, and sometimes you have to give it a chance.
All the very best with whatever you choose
