Since its opening nearly three decades ago, San Diego’s Ronald McDonald House (RMHC) has provided more than 120,000 nights of lodging for more than 12,000 families whose children are receiving treatment at area hospitals for life-threatening illnesses. However, with only 12 rooms, it turns away 100 families each month. So RMHC is now in the midst of a vital $15 million capital campaign to complete a new 65,000-square-foot house project with 47 rooms. (858/467-4750, www.rmhcsd.org)   JANE SHIOMI
