If you are comfortable enough with your identity and tastes and can say loud and proud that you enjoy some fried Spam, congratulations on stepping into the light. (And you may want to hit up the Spamley Cup competition this weekend.) If not, stop lying to yourself. Take the first steps toward self-acceptance at the Alibi (744 Ninth St., Arcata). On "Trailer Park Mondays," as noted on the laminated specials menu, a Spam burger can be yours for $6. Two thick, round-edged slabs of the pink stuff arrive with cartoon grill marks on a grilled whole wheat bun. Whole wheat. (Tosses head back, spins in chair, cackling.) Do you want the lettuce, pickles and raw onion on the side? Maybe. The mayo in the little, white cup? Likely. The meat is soft and salty, the fat enlivened by grilling, all of which is nicely matched by the sweetness of the bun. Sure, the iconic canned lunch meat is full of iffy chemicals and so processed that we need a new word for processed. But in that rare moment when home-pickled organic beets just won't satisfy that 1950s bomb-shelter cuisine itch, the Spam burger is the way to scratch.
