And yes, those lobsters were some good, and at times, some cheap! I bet they taste pretty similar to Nova Scotia lobsters, though. I haven't had lobster since I moved away. If it's more than $5 a pound and wasn't in the ocean the day before, it's just not worth eating. Those little shacks on the side of the road -- they had the BEST lobster!
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
