Just had a nice text conversation with Tracker for the last 32 minutes. He is doing well and still snowmobiling and guiding trips. He said to say hello to you old abe. He thought the site had closed. I told him to jump on sometime. He sent me a youtube short film about a project that he made the Faraday cup on and figured out how to cut the graphite foam and he made the nozzles. I will see if I can get a link posted tomorrow.
