This is at a friend's house, I haven't seen it in person, just have these pics (sorry, it's not much to go on). Can anyone tell what kind of tree this is? My guess was black locust

Hard to see the bark from that distance but I don't see BL....maybe Honeylocust. the twig color should ring a bell with someone but I haven't seen much Honeylocust.
 
I'm going to "guess" honey locust. The top picture appears to be a single leaf, which means it's double-compound, which means it's HIGHLY likely to be honey locust.

That being said, without closer pictures of the tree, a scale in the leaf pictures for size-reference, and knowing for certain that it's a double-compound leaf or a twig full of compound leaves, I can't be certain.
 
black locust. honey locust have long spikes
It's honey

Black Locust is a single-compound leave and has deeply furrowed, coarse bark that is quite thick.

Honey Locust is a double-compound leaf, has somewhat smooth, sheet-like bark, and may or may not have thorns (there are thornless varieties mainly marketed for landscaping etc)

With the recent addition of the picture of the bark my guess was confirmed. The leaf, is, in-fact a double-compound honest locust leaf. You will notice on the latest picture that the "knots" that the thorns typically grow from on Honey Locust are present and there may be some thorns present.

thornless honeylocust (Gleditsia triacanthos inermis)
There are several cultivated varieties of thornless honeylocust (e.g. Skyline)

Black locust bark is thick and blocky (see image above), and wood smells like peas (like legume) when fresh cut.

The image in post #5 isn't black locust. BL has lumpy, rough bark, instantly recognizable even from a distance. Dad used to call it the ugliest tree he'd ever seen.
