Caitlin & Mark in Grayslake, IL

It took Mark an entire summer working with Caitlin to ask her out on a date. When they did go see Finding Nemo at the movies, and Mark laughed louder than the little kids in the theater, Caitlin started falling in love with him. With their colleges four-and-a-half hours apart, neither one was sure what would happen, but Mark played his guitar and sang Caitlin a song asking her to be his girlfriend at the end of the summer. The Bride Caitlin Vishoot, 26, marketing coordinator The Groom Mark Santa Maria, 27, structural engineer The Date September 28 Three-and-a-half years into their mostly long-distance relationship, Mark drove from Chicago to help Caitlin move out on the day she finished graduate school. That night they hopped in the car, Caitlin thinking they were running errands; instead, Mark drove to an arboretum near campus. Beneath a trellis, Mark proposed. They spent the next year-and-a-half planning an eco-friendly and mostly DIY wedding with a relaxed, vintage style.
