Pearson - 1996 7 paperwork because La Riviere himself must approve the trapping of rare or endangered species, and Octodon has been so declared in Lanin. Since it does not officially exist yet in Parque Nahuel Huapi, no special permit is needed. Then the two young guys from the 4th Public Health District came by and wanted me to meet with their boss at 2 p.m. Then Lorenzo Sympson came by. He is working as a free lance tour arranger and guide. Fishing, wildlife, ranching. You tell him what you want to do and he chooses an Estancia for you to visit.

Her house was at the edge of a dump full of branches, plaster, broken tile, cans and bottles, etc. Not much "food", and no chimangos or gulls hanging around. They want me to see what I can catch nearby. Anita and I went out with traps at 6 p.m. Quite a few people and traffic, so a bit iffy leaving traps there.
