With summerlike weather in the forecast, 4GoodVibes is kicking off the sidewalk pop-up sale season at its South Medford store. Most weekends the store will have local artists/vendors set up in front of the store store selling their items. Some weekends will feature vendors sampling food as well. Stop by today or Sunday, also between 11 a.m. and 3:30 p.m., and see what’s available for last-minute Mother’s Day gifts.
