When you get up to West Yellowstone, stop in Blue Ribbon Flies (Craig Matthews) at the north end of town going toward Bozeman. He is a great Tenkara fisherman and his fly shop supports Tenkara big time. He will point you in the right direction for some quality fishing in and out of the park. Grab one of his catalogs and read the article by Yvon Chouinard about Tenkara.
If you are in the are July 14th come on down to Bozeman. Fin and Feathers Fly Shop at Four Corners is hosting a Tenkara Clinic with Daniel Gallardo (http://www.finsandfeathersonline.com/bl ... nkara-day/
). Four corners is the first stop light north of West Yellowstone about 90 miles away. Fin and Feathers is a good Tenkara dealer also. Ask for John.
Have a fun trip and a good time. Carry bear spray (one each for everyone), don't try and pet the bison.
