I'm in Fresno, I checked Trader Joe's, Costco and three other local Grocery stores. Next time I will just pop over to the Mexican grocery, I know they have them. Just takes a bit longer to get there.

I recently moved to California from Oklahoma and went looking for Key Limes here ( I once lived in S. Yorkshire), they made a one week appearance at a Mexican grocery here. Other than that, no such luck. I have substituted persian lime and lemon juice mixed about 1/2 each along with the zest from each. Really a matter of personal taste. Plain HobNobs mixed with graham cracker make the best base (the more HobNobs, the less likely it will get soggy)If it stays around long enough for that. =)
