We would love to see your kids on the 31st for games and bonfire! We'd like to ask local families to try to set up a sitter for the wedding - enjoy a date night! Also, please keep in mind you will be on a working farm -- don't let your kids sneak off into the barn and ruin the tractors. (Or hurt themselves.)
Yes, the farm is in the country. There will be plenty of parking.
Smart casual - we want you to look good while being comfy! Don't go over the top - stilettos and a tuxedo would be a bit out of place on the farm, but look smart. Bring layers in case the temps are chilly. Keep in mind you'll be walking in grass most of the time so bring flats or wedges along with your dancing shoes!
Possibly.
