Do I use "where" or "were" in these sentences?
Thankgiving is a season were we are able to visit family and eat alot.
In a season were our economy is not very good.
It's certainly not "where" but I'd suggest "when" or "in which" instead of "where."
Note that "a lot" is two words, and Thanksgiving is a day not a season.
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.
