Literature (prose & poetry alike), religion & philosophy, history, photography (B&W and night photography in particular), movies, music (from opera and symphonies through the big band era up to 60's and beyond, jazz, assorted country music, trance & rave & acid & house, good old hard rock and much, much more), writing, airports, flying, beauty of the forest, flow of the water, women, intelligent conversation about almost anything... not enough yet?
