Now the usual way to go about this is to look for an unusual number of cars or pickups, or look for large numbers of tire tracks. If it ain't a church or convenience store, that means that something hinky is going on there, be it a dog fight or a bootlegger or a undercover strip show or a seller of hot goods that fell off of a truck. Some guys just have a nose for such things, so to speak!
Well, the boys were wearing work clothes; and darn it, they looked respectful!
So much so that the old lady who was running the suspicious joint that they thought was running a bootleg joint asked to see their driver's licenses! Now that's a turnabout; getting asked for I.D. before they could enter a bootlegger's establishment! Like it was a respectable place and she wanted proof of age!
Well, Billy Bob's mind was trashed; he was quite a few years older than 21 and hadn't been asked for an I.D. in years when it was an issue! But Bubba showed his, and gained admission. The old lady just wanted to make sure he wasn't a local deputy acting undercover. The North Carolina driver's license sort of did that. So Billy Bob showed his. Having proved they were from out of state and not deputies gone undercover, the boys were admitted.
[A long time ago, bootleg joints were sometimes called blind tigers.]
