Paperwork signed!
Praise God my paperwork from Cameroon has been signed! Now that we have that in hand, we can actually apply for my visa, the final step. Though that process is a bit more predictable because it is here in the US, we are pretty tight on the time generally expected, so Please continue to pray that all will fall into place. God’s timing is perfect!
Further updates: I have returned from my roadtrip. I ended up not staying quite as long as originally expected because I wimped out . . . Imagine my surprise when i woke up to ICE on my tent! That and a bit of a SNOW storm that morning as I drove across the park. 
Crazy, huh?! Likewise, when I was camping in the Black Hills there was a beautiful thunderstorm (though obviously not conducive to camping). 
I am currently in Omaha, where I will be staying (with my parents) until my departure.
