a hot air balloon rally has become a 4th of July tradition in Lexington. It's now in its 18th year, and thousands of people are expected for the four-day event. WDBJ7's Joe Dashiell is here and Joe you found one couple who will always remember the rally. Chris, Independence Day began with an engagement, high above the Parade Ground at Virginia Military Institute. Strong winds aloft prevented the hot air balloons from launching this morning. So Ben Shehan had to improvise. But it all worked out when he and his girlfriend Brooklyn Jarvis took a tethered baloon ride early this morning. Ben Shehan: We were talking how beautiful it was with vmi in the background. And she turned around to take pictures and she turned back and i was down on one knee with the ring out, and asked her to be mine forever. Brooklyn Jarvis: No clue, but I'm still shocked and I'm shaking. I'm just glad that my family was here to see it and share this time with us. And that was a major benefit of the tethered balloon ride. The couple's family and friends were able to watch the proposal from the ground. And for the record, Brooklyn said yes. That was just the beginning of a busy Independence Day in Lexington. We'll listen to the Declaration of Independence and ride along for a children's event that just seems to get bigger and bigger every year.
