It sounds like she had a ball! Socialization early on is a great thing and I'm glad she handled it so well, but...
Judging by her age she hasn't received all of her puppy shots yet which are a must before taking pups out in public where other dogs could have been or are! They can pick up deadly diseases from the ground before they get all their vaccines so carrying pups in public is a good idea beforehand to make sure they still get all their socialization, but no risk of disease.
I would watch Eva like a hawk until she gets all of her shots. Look for lethargy, loss of appetite, bloody stool, or vomiting. First sign of any of them and I'd get her to the vet asap for a parvo test.
To your original question; yes, we take our dog out to events all the time. For parades, get togethers, dog events (expos, halloween contest parties, etc), and just out to the store for training. He handles people great and loves dogs but can become reactive around them so we keep our distance until he's calmed down a bit.
