It was a large woody shrub or small tree, typical citrus-like foliage,
lots
of hellacious thorns on it, and several lemons that were hard and didn't
smell
like the common edible ones, although did smell sorta citrusy.

You are describing Poncirus trifoliata. It is sometimes used as a
rootstock to
improve the hardiness of citrus trees. Its fruit is not edible. There is a
cultivar called 'Flying Dragon' which is sold for ornament & occasionally
used
for bonsai.
