Alright guys here it is: What is your favorite testing environment?
There are so many options that are not in here that I test daily at, and then to only have to choose one over another?
I see your point, but I think sometimes it helps to limit the options…to force someone to choose between two favorite environments.

Yepp tourch already got there before you did bud 
But what happens if my favorite places aren’t there?
Here’s what I suggest: Ask the users what their favorite places to test are and why. Then when you have a general idea where these places might be, and believe me you’d be surprised where some of us consider favorites, then compile the poll from those results.
Just a suggestion, but I believe you would get much more participation

Two of my favorite places to test (not included)
Grocery Store
Coffee Shop
I like to test it at yo momma’s house!.. oooo need some water for that nasty burn? (yep you guessed it I’m a jackass)
