My parents would still do the egg hunt with us, assigning certain egg colors to us so it was fair. As we got older, the locations were more challenging (the tips of the ceiling fans, wedged in the spokes of the bicycle tires that were hanging in the garage). But always, there would be 1 egg that would either contain money, a check, or a ?.
The question mark was usually a giftcard to a store or movie theater.
