We did not register anywhere. On our website we do have a "registry" link where there are somethings that we picked out. We'll also have a card box at the ceremony (which is what we prefer).
Cocktail Attire/Business Casual. Nothing too fancy, ceremony and reception will both be outside. Slacks, button down, tie optional. ATTENTION LADIES: You will be in the grass so be selective with your shoes if you're wearing heels! :)
The invitations were specifically addressed to the persons that we expect to come
Yes, find the Valet guys. Valet is free
Ceremony starts at 4:30. I would say no later than 4:15
