Have him then go to Fly Rods under Gear. 2nd from top left under Big Y Nano click down arrow and click on 590-4 (4 piece, 5 wt., 9 foot nano material graphite rod). This is a GREAT entry level fly rod. I have one and use it ALL THE TIME. Durable and almost unbreakable. Warrantee is as good as the big boys like Sage and Orvis but is much cheaper.
While there look at Adams, Amy's Ants, Blue Wing Olives, Bugmeisters, Henry's Fork Hoppers, Half Chernobyls, Purple Haze, Stimulators for dry flies,
Hares ears, Pheasant tails, Caddis pupa, Golden Stoneflies for nymphs,
Black, Brown, Olive, Ginger Buggers for streamers in LARGE sizes (2-8 if available) and purple Moal Leaches for streamers
My friend Harold buys all of his flies here. You will meet him on the Missouri. Great flies and CHEAP. 2 or 3 of select patterns will do. Shipping is FREE with orders over $35.
They also have waders with stocking feet (will need felt sole boots) and wading staffs (which I have used for years in slippery stream to traverse across).
