The most notable characteristic of the Ruffed Grouse isn't how they looks -- it's how they sound. In the spring and a little in the fall, the male ruffed grouse beats the air with his wings to make a loud drumming sound.
expired test strips are NOT reliable. most strips have an expiry date over 2 years from the date of manufacture...... that's a long time for them to be 'sitting around'. as for e-bay........
Taking all of that into consideration, I think most strips, if stored properly, can be used for a good period of time beyond their official expiration date. There's enough of a cushion built in that we can stretch it, and not get a mouthful of spoiled milk.
