Hi, Amy - this is a great topic. The Wadsworth Atheneum in Hartford, CT, a few years ago switched to having all of its "guards" (I now hesitate to call them that) walking around with tablets, headsets and dressed in T-shirts that say, "Ask Me!" They can show you the map on the tablet if you're looking for specific objects or exhibitions, (nearest lavatory?) and (as I recall) even link to the museum's online catalogue... When I first visited after this switch, they were all smiling and inviting. I thought it was brilliant. Whoever thought of it should be celebrated. Vivian
