I found this thread interesting.....I have been here in The Villages for 3 years, and have never thought too much about using my gate card in the rain. After all, there are MANY gates without a person at the gatehouse, so you have to use your cart for entry (or push the red button to speak to an attendant).
So what if our arm gets wet? It's rain! It's ok! You will dry off sooner or later!
