SMA PLT ENTERS TEMPORARY RESTR AIRSPACE WITHOUT CLRNC.

Narrative

I WAS FLYING VFR WITH FLT FOLLOWING. UPON DEPARTING ZZZ; I CONTACTED ZZZ1 FSS FOR MY ENROUTE FLT INFO AND THEN CONTACTED ZZZ2 CTR ATC FOR FLT FOLLOWING. AFTER BEING HANDED OFF TO VARIOUS ATC'S; I WAS IN CONTACT WITH ZZZ3 CTR AND THEY STATED I WAS LEAVING THEIR COVERAGE AND WOULD NEED TO CONTACT ZZZ4 APCH FOR FURTHER COVERAGE IN TEN MINS. TEN MINS LATER I CONTACTED ZZZ4 APCH. AT THIS TIME I WAS INFORMED THAT I WAS IN A TEMPORARILY RESTR AIRSPACE CALLED ZZZ5 ARMY DEPOT. AFTER LOOKING OVER MY CHARTS; I STATED TO ATC THAT THIS TEMPORARILY RESTR AIRSPACE WAS NOT ON THE CHARTS AND I WAS NOT INFORMED BY EITHER ZZZ1 FSS OR ZZZ3 CTR THAT I WOULD BE ENTERING THIS RESTR AIRSPACE. ATC'S REPLY WAS; YES; HE KNEW THE AIRSPACE WAS NOT ON THE CHARTS AND THAT I SHOULD HAVE BEEN ADVISED BY EITHER ZZZ1 FSS OR ZZZ3 CTR ATC THAT MY DIRECT COURSE AND ALTITUDE WOULD CONFLICT WITH THIS AIRSPACE. I FEEL THIS PROB COULD HAVE BEEN AVOIDED BY EITHER HAVING THIS RESTR AIRSPACE ON THE CHARTS OR BY HAVING ATC'S AND FSS ADVISE PLTS ON DIRECT HEADING CONFLICTS WITH THIS AIRSPACE.
