I am thinking about growing some vegetables this summer in container gardens-I live in a townhouse. What sort of vegetables are good for this? I love celery, radishes, carrots, tomatoes, etc. but picking seeds is a new thing to me. Any recommendations?

I don't have any luck with seeds. But if you want to try, plant seeds, according to packet directions, in small pots; keep inside in sunny location. Transplant to large container when at least 6 inches high. Or just go to a nursery for seedlings. Try cherry tomatoes - I've had success with "sweet one-hundreds"; plant a couple tomatoes along with a marigold or two as a sort of organic pesticide to dissuade aphids. Don't forget a support for the tomatoes - put a tomato cage around the young plants. If you like eggplant, try Japanese eggplant. Both plants are easy growers; keep in large, separate pots. Both are sun lovers. Other sun lovers are herbs. I have oregano and thyme growing in a nice strawberry container. Just make sure with all potted vegetables that you have proper drainage or you'll have root rot. Have fun!
