I know this thread is from earlier in the month, but I thought that I would post what our pack has started doing. In the fall we set up a table at Back to School Night, but in the spring we started hosting an open house in conjunction with out Pack Olympics. Prior to the event we send letters home to the local elementary school kids, and we also have the local newspaper include it in upcoming events so that we can get homeschoolers and those in private schools who might be interested.
