So you pitch a tent and I put a studio in it.... well, no.
I don't know what to tell you. First, was the garage your idea? Isn't it going to be a bit cold in the Chicago winter and perhaps a wee bit more susceptible to theft? Do you want to record in the garage? Will it hamper your inspiration or will you always be a little ticked off about it? Will you be happy there? Will the garage door rattle when you record? Is this what you really want? I think it matters in the long run... it would for me. I can't pretend to know you Mooch but you seem well liked here. So I assume you are a good guy... besides the Bapu connection
I just hope, all kidding aside, you are happy with this so it don't become a problem down the road when any and everything can be a problem.
