* Capacity is limited. Advance reservations required at most farms and time slots sell out in advance.
* Be prepared for lots of walking in uneven, possibly muddy terrain. Think boots, layers and baby carriers instead of strollers.
* Bring cash, lots of it. Most farms don't take credit cards and all the food and activities add up quickly. If you're just there for the apples, make sure your kids know that in advance.
* Call or check the farm's website to confirm apples (sometimes they are picked out) and activities are available.
