t's a Wednesday. There's not much going on in the way of nightlife and the only major concert in town is Rod Stewart. Why not take the opportunity to do something for the kids? They don't even have to be your kids; just grab some kids and take them to the International Balloon Festival of Saint-Jean-sur- Richelieu. The event's popularity has risen steadily (no pun intended) since its inception in the '80s, now attracting over 350,000 visitors per year. The 115 hot air balloons come in all shapes and sizes, including balloons modeled on cartoon characters and the fleur-de-lis. You've even got people in jet packs (that should be the selling point). The festival continues until August 17, but tonight's festivities include a performance by folk-rockers (and Neil Young apers) America.
