Well dammit. I went out for a late night run and was gonna try out the Pbox, but 2 things didn't pan out. I realized I only have an XD card and not SD card.
And from my place in the city all the way to the frontage road I was gonna use about 10 minutes south of SF, I could never pick up a satellite signal. Do I have to go out to the boonies?!
I did however test the frontage road and do believe I can get to 130 and slow down before the curve. Pretty sure anyway...
