My parents are throwing a party to celebrate their 70ths in a month or so. They are very physically active, and social and fairly non-materialistic. Last big date I got them a grandchild but I've run out of shopping days. Ideas? via /r/Gifts https://www.reddit.com/r/Gifts/comments/7oo0aq/gift_for_parents_joint_70th_birthdays/?utm_source=ifttt
