The average blocksize is roughly 500 bytes, so at one per minute, you get ~720k per day.  Then there's the normal network hand shaking and transaction relaying on top of that.
The nodes that are "spamming" with orphan blocks are also causing a high volume of getblock requests which appear to be creating the abnormal network traffic.  I'm currently debugging it, and may need to issue another release if the nodes do not get on the right chain soon.

Might be coming from my 
mom's/dad's wallets since it says NJ
I will have them reload blockchain
Update
It was my dad's wallet. i know he has his computer set to sleep after 10 minutes and doesn't run his wallet 24/7 could this be the cause?  He doesnt want to run his computer all day since his electric $ is more then he makes in coins a day.
But if it helps i will try and convince him to run 24/7
what should i do onsight?
