Get your students out and away from your church campus and watch them grow. If you have a small group you have an awesome opportunity to take them all at the same time. If you have a larger group, take them in small groups, ministry teams, etc.
Contact local business and ask about "slow-times" and get a deal. You could also plan a free day trip, like a video scavenger hunt at the mall (call to set this up ahead) or Frisbee golf at a local park.
Get your students out together and relationships strengthen and grow, for all involved!
