Greg Williams met Alyssa Crick in 2008, at a Halloween party in Allentown. She was dressed as a giant S’more. And all evening long, smiling at him in her marshmallow costume, she made him hold her giant graham cracker hat.

It was only natural, then, that after their wedding June 7 at St. Amelia Church in Tonawanda, they danced to James Taylor’s “How Sweet It Is.” And that the reception, at the Buffalo History Museum, featured ice cream and baklava.

Crick, a graphic designer, also added a treat to the wedding invitations, which she designed herself. A map directed guests not only to the History Museum and St. Amelia’s, but to the site of that Halloween party. And to the Globe Market, where they had their first date on the Wednesday before Thanksgiving.

Also on the map was the spot on Delaware Avenue where Williams proposed one snowy December evening.

“Her work party was at the Avant,” he said. “I had planned to propose before, hopefully while walking the streets of Buffalo, but we got this nasty snowstorm. I was running incredibly late from work. And the snow was so bad, you could hardly see. She was going to catch a ride with a friend, I’m like, ‘No, I’ll be there.’ That was five o’clock. Six rolls around. I said, ‘I’m on my way.’ ”

As the storm intensified, so did the mystery. After driving them downtown, Williams refused the valet parking and parked in a nearby lot.

“We were walking to the Avant building with the snow just blowing horizontally and all of a sudden he stopped and said, ‘Hold on a second,’ and got down on one knee,” Crick recalled. “It was such a winter wonderland. It made it even more fun.”

Bride and groom both love nature. The Cape Cod house they chose in Gardenville backs up to a wooded area. “There are tons of animals,” Crick said.

Williams is a rock climber, and since meeting him, Crick added, she has climbed seven mountains in the Adirondacks. “He’s made me more adventurous,” she said.

So adventurous, in fact, that she was even a good sport when a back-country camping trip turned scary.

“She was really nervous about the bears,” Williams said. “I’m like, ‘Don’t worry.’ And of course, we had a bear try to get into the tent.” He got it to go away. “I back-handed it in the face,” he said. Luckily, the bear had not gotten far. “His head was poking into the tent.”

The bear must have smelled a marshmallow.
