DH doesn't drink, but it never posed an issue. You can do pretty much anything while not drinking. Hiking, dinner, movies, theater, opera, walks in the park, food tours, street art tours, bike rides, whitewater rafting, paint-your-own-pottery, museums, improv shows, art festivals, concerts, open mike nights, visit a historic graveyard, go to a poetry reading, attend a live literature event, visit a planetarium, go actual stargazing, take a cooking class, cook a meal together at one of your homes, go to a sporting event. You just do the thing, and <here's the trick> consume no alcohol.
