We'll be in New York City for a holiday for a week in October. Are there any cool Ham stores or interesting radio related historic sites/museums that I should try and see within easy reach?
@OH2XAB There are some beautiful buildings that were telecommunications hubs back in 1920-1940, and some of them are major Internet sites. The High Line is a wonderful walk, and continue on south to see the original Bell Telephone Laboratories. I have a page with pictures and explanations:

Internet Infrastructure in Manhattan

How to see the physical elements of the Internet. Lower Manhattan has been a world-class telecommunications hub since the 1920s. The Internet lives in these historic and modern buildings.
