Two 8.2 ASA's are set up with a site-to-site VPN tunnel between them, as can be seen in the diagram:

Here is my configuration for both.

Clients on the inside network of either ASA cannot ping clients on the inside network of the other ASA. Why not?

When pinging from the inside network of SALMONARM to the inside network of KAMLOOPS, the following debug logs can be seen on SALMONARM:

%ASA-7-609001: Built local-host outside:10.30.7.2

Each ping attempt responds with "Request timed out" on the pinging computer.

Why can't clients ping each other over the VPN tunnel?
