Music: Jazz, Classical, Rock. Think Miles, Coltrane, Buddy Rich,
Oscar Peterson, Bechet, etc. Then think about Tchaikovsky, Holst,
and Beethoven. Finally, think Boston, Kansas, apparently bands
named after US places.
TV: Shows like Psych, Sherlock, BSG, Burn Notice, Firefly, Boston
Legal, Hustle, GoT, ...
Literature: Most of my reading in non-fiction [read: science] but I
do try to squeeze some time in for classics, sci-fi, etc. Currently
soaring through The Count of Monte Cristo and re-reading the LOTR
with the Silmarillion because I missed it the first time
Food: Mexican and Indian in particular, things with food in
general. I also enjoy various whiskies: bourbon [I figure since I
live in TN I should familiarize myself with bourbon] and scotch.
