Concealed?

[FireMed]

I have a question, a sincere question and I'm not being a smart ass, nor do I think I am stupid.
I obtained my first carry permit while living in Texas. I was 55 years old when I moved there from Canada in 1996. My gun was always in my vehicle.
I moved to Tennessee in 2000 and married. I was able to obtain a Tn. carry permit due to the reciprocity with Tx.
My firearm now, is always in the truck unless I am hunting deer or walking the dog after dark.
I am 6' tall and 215 lbs. and 99.9% of the time I wear blue jeans and a golf shirt.
How in the hell do I carry a firearm concealed????? Really, where do I put it?
