my sister looked up post office is open till midnight Tuesday, April 18, 2017 and it showed the March reserve base post office being open until I think it was 11:59 PM So I used Siri on the phone in following her directions got on the freeway got off on Cactus Avenue, and following its directions just before I was supposed to turn left came upon huge concrete blocks in the road and a chain-link fence. I don't know if it was razor wire or not on that fence blocking me from where the post office would be on Graeber to the left where I saw bright white lights which I thought could be the post office at about 11:15 PM Not knowing how to get around the fence I drove on to the Menifee post office which I was insured was also open till 1159 only to find it closed also I was there before 11:47 PM only to find a closed Driving back home I went back to cactus and look for the entrance to March Air Base. Finding it I informed the three guards that when people are looking for the March post office the phone Siri service direct people into concrete blocks in a chain-link fence. The cards were very nice and polite but they said they could do nothing about that Siri that directs people into a chain-link fence in concrete blocks. I suggested they contact the Marji airbase do you know IT people tech people so they could contact to Siri services and let them know that where I got stuck at the concrete blocks in the chain-link fence isn't a through road so they could route people correctly. They were insistent that wasn't their job. Well that maybe true they missed the entire point that citizens are being directed into a blocked location when trying to get to the post office and how hard is it for them to contact the IT offices who may know how to get through to the Siri computer folks that make those maps, to put in a correction so they know they cannot get through at that point. It is just common sense to try to fix the missed directing around March Air Force Base by Siri. I made a feeble attempt last night to get Siri to transfer me to somebody and it didn't work but I assumed March Air Force Base might have some high-tech people that would know the correct way to get through there by eating people who want to get to the post office Of course since they were guards at the gate perhaps regular citizens are not allowed at the post office I don't know but all that should be made clear when people you know are searching for a post office in that one pops up I am also going to try to contact that particular post office but to me March air reserve base is a bigger entity and likely has better IT people to contact and make this correction
