Is there someplace, or maybe some thing that you know like the back of your hand?

I know myself very well:)
Aside from that,I know the rivers and lakes around here quite well and only get lost occasionally snickers:)

Algebra I and II and Geometry.

Disneyland. I know every nook and cranny of that place.

I can also get to any place in L.A. via any freeway. I know all the connections.

I know how to pee standing up like nobody’s business.

WAIT! I misread! I thought it asked is there some place or some thing you’d LIKE to know. Sorry ‘bout that.

I used to know the woods around my childhood home like the back of my hand. Even not staying on the path, I always knew where I was and never got lost. Found a lot of wonderful spots and knew all the possible ways to cross the creek without getting wet. I found places deep in the woods that had been used to dump appliances, and once even found an old car. Another time I found a pile of bones. It looked like someone who hunted deer would butcher them out there, or maybe just dump the carcasses. Some were, um, fresher than others.

Considering how directionally challenged I am in any other setting, I was always amazed at myself for not getting lost out there. Technically I wasn’t allowed to go into the woods, but my parents both worked and so weren’t home to stop me. They then told me to never go off the path, but what’s the fun in that?

The town I grew up in. It’s small enough to get to know easily.

I wonder how many people can accurately describe the back of their hand or even pick it out of a lineup of similar hands with 100% confidence.

My grandmother’s street in Montreal. Downtown Cincinnati. The XML code for our products at work (I’m not a programmer.)

Mulholland Dr.
Piuma Rd.

There is a body part (not mine) that I know so much better than the back of my hand.

I could identify it from among 50 other such parts belonging to others with little chance of error.
