Change Log Path for Squid on Centos 6

I searched and did not find a useful answer. Can someone please tell me the best practice to change the log directory from /var/log to /opt/squid?

$ grep "/var/" /etc/squid/squid.conf

# cache_dir ufs /var/cache/squid 100 16 256
access_log /var/log/squid/access.log squid
# cache_log /var/log/squid/cache.log
# cache_store_log /var/log/squid/store.log
# pid_filename /var/run/squid.pid
coredump_dir /var/cache/squid

$

My Squid logs are all under /var/log/squid but I see no mention of that directory in /etc/squid/squid.conf.

Which is why I posted the information from my squid.conf, which came with comments on every possible option, even the ones not set (in comments).

If those options aren't set in your conf file, set them. In their absence, they default to /var/log/squid...

What do I do to move squid.out? That file seems to be different than the access.log and cache.log files.
