Narrative:

Approaching leets, an aircraft called in behind us, so I decided to take the first highspd taxiway F6. As we were exiting taxiway F6, the tower told us to take taxiway F4. Taxiway F6 was notamed closed and was closed on the ATIS, but had no markings, men, or equipment on it. I should have checked NOTAMS and read all of the ATIS.
