Attend picnics, parades, parties and firework displays on July 4th (US). The holiday is on a Wednesday, which really cuts into celebrations. Some people will celebrate the weekend before, some on the holiday itself and others the following weekend. This provides you with endless opportunities to network with new people. The great thing about this particular holiday is that most events are free. You never know who could open that all important door to a hiring authority who could provide you with a job offer!
