Joe, in this neighborhood there will always be those who just can't seem to have fun with a discussion and simple questions. You don't have to defend yourself at all and you didn't deserve the wise ass remarks. However, be prepared to get the same thing once in a while from the same neighborhood and let it roll off your back. As you can see, there are those who will have a decent discussion about your topic. Good pics by the way. I have to rely on the electronic cameras and hope they produce a good photo! Have fun, and go visit your local fields!
