I'm looking for a tool to allow me to see what is within X nms or X hrs of my base airport. Is there such a thing? I remember a small airport I flew to once had a large map with a string attached to a pin located at the airports location on the map. There were concentric rings from the location stating 100/200/300....nm. I'm basically looking for something like that such that I could explore and look for locations that are off my normal radar of places I would typically visit. I typically use landings.com for baseline flight planning but you need an origin and destination. It doesn't look like it allows what I'm asking for. 

I'd even be happy if there was a hack for google maps etc. to do what I'm asking.
