At InTouch.org, they're doing a sign up to pray for our nation for 140 days beginning on July 5th.
There's a link (pasted below) where you can sign up. You'll receive a weekly email with the scripture focus and the subject being prayed about that week. You can also download a PDF file which gives an overview of the topics covered for those 20 weeks.

Have a great weekend!
