Welcome brother crow :lbw1
You have asked a pretty important question, that concerns most people living in North America.
The Qibla is actually SouthEast. Just like you did, if u look at the map, you see the Ka^bah in the SouthEast of North America, that's where u are.
I also live in N. America, in the US, and I agree with you, there are A LOT of mosques where they stand in the wrong direction, and MOST of them are wahhabis, the others are just following the rest, they see their direction North East so they follow... However, there are also a lot of mosques with the right direction, ie SouthEast. I think MOST of the ones in California are right. So watch out bro

the Qibla is SouthEast, not NorthEast in North America.
As from where they got this idea, originally few engineers made calculations on which is the shortest way to go from North America to the Ka^bah and they found out that the shortest way would be NorthEast, so they started praying toward the shortest way to get there, however it is not right, we pray in the direction of al Ka^bah NOT toward the shortest way to get to the ka^bah :lbw1
I hope I answered your question
