Man! They got em' on that truck in Austin and out to San Angelo in a hurry! You said you were 4 hours from Austin, They arrived in Austin at 5:55. Let's be unrealistic and say they got the speakers on the truck at 6AM , and they got to San Angelo at 8:20? No Texas county mounties on that road. Cool.
Shoot it's 10:25 now. They're either on your porch, or still on the truck for tomorrow. Hope it's the porch!
