Update! I removed the trap in the basement after knocking on the pvc pipe down there and realizing it was full of fluid. Lots of nasty shit came out (mostly turkey). However, the clog is still below the trap. I put the trap back in and put some Drano down the sink to do some work tonight.
I will have to go to home depot tomorrow and get an auger. I wasn't getting the cheap one at Walmart.
