Only sissy campers go home when it rains. In September of 2008 I camped when we got 9" of rain from Friday evening to Sunday morning! My kids and I talk about that trip to this day.
We have a bad reputation of whenever we camp we have terrible weather. Our pastor asked us once whether we were camping on the next long weekend as he wanted to know what the forecast would be.. Apparently we are more accurate than the Farmer's Almanac!
