Hi Pengs5. Was in that area at Bozeman a long time ago. 1991. Professor Jim Sims from the state university at Bozeman took my brother and self up through Helena, Great Falls and up to Big Sandy for a couple of field days where we gave the locals a run down on what we were doing with medics and the nitrogen fixation they were giving us. Went onto another FD's at lewistown where Rolf, who had been driving headers for Marvin Gorden across Oklahoma and Kansas caught up with us. Rolf took us back down to Billings and then onto Bismarck, Fargo and down onto Denver. Some nice country around Bozeman and Billings. Went on from there to Canada, Chicago, the UK, Sweden, Finland, the USSR[ at that time! ] and onto home. A good trip. Will catch up with you some time. My E-mail is up near the top of the current postings. Cheers.
