Your Wolf sighting was far more glamorous than mine. He sat behind me on an Amtrak regional train slowly crawling to New York during the middle of a blizzard about eight winters ago. There was so much ice and snow that the crew had to struggle to open a single door at each station. Our 90 minute journey took 3+ hours. He and his wife had been on since Washington for some unimaginable length of time. Nice guy.
