MMM, are you thinking something like a destination? Maybe a charity? Everyone meet and end up at a local APL with cash donation, even a modest amout is appreciated and goes a long way. Or something more girly, maybe to a spa or salon and get tips on sun and skin care for women riders, maybe to a dealership to see hair wrangling products.
Sometimes just riding and going for pie is enough.
Hope for the Best. Expect the Worst. I am rarely Disappointed.
