As happens every so often, the Carnegie Museums of Art and Natural History are offering free admission on Thursday evenings.

The offer holds for four straight Thursdays, starting this week. Admission is free those days from 4-8 p.m.

This might be a good time to take advantage of the offer, as we've heard there's some sort of large exhibition of international art going on right now.

It's also the final week for the Natural History Museum's big Roads of Arabia show.

The museum credits the free days to board member and philanthropist Richie Battle.
