I agree with all what SG said except one thing. I actually find farmers in better moods when its raining unless of course they need to be in the fields and can't because of the rain....maybe its a midwest thing. The reason is when its raining, they are less likely to be busy with chores. Timing is very important. During good weather when working the ground and planting is taking place, don't bother the farmer. He has enough on his mind in that time period watching the weather and making sure the machinery is not breaking down. Also, just after crops are starting to come up and deer are seen eating new plants, the thought of having someone rid them of some deer can be of help.
