Well, the other two spark indicators were delivered yesterday: one in Tennessee, and one in Mississippi. Gotta love USPS. Same address on both. USPS' attitude is that I should just go get the packages. Not that I know where the packages were delivered. What good is a shipping company, if they can't deliver, but expect you to do their job?
I did get several packages, today, but none are for me--or for this address, city, or state, for that matter.
