Have not bought a fly in over 20yrs.
A Brit (USAF), I was stationed with in England taught me how to tie. I don't think he ever left the UK, except maybe for basic and tech school, and maybe a TDY to Hurlburt Field. He was friends with an angling shop owner, who hooked me up with tons of fly tying materials for free; full metz capes, dubbing, tinsels, thread, floss, etc. Since most of the fishing I have done since is trout, I have used a lot of the hares ear, pheasant, elk, deer, so I need to get more of those types of materials.
Just getting back into fishing after a few years of not being able to due to family issues (in house care of MIL with dementia, finally passed late last month). Got both of my rods and reels setup yesterday. My first rod that I bought in 1991 is a 4wt 8.5ft made by High Sierra Custom Fly Rods in Nevada, I don't think they are around anymore. It's matched up with a Sage reel. Second rod is a Sage 6wt 9ft, paired up with a Rimfly Concept reel I bought in the UK way back when.
It's some old equipment, but still works great, and has caught vast amounts of trout, bass, and panfish. I see no need to go out and buy the latest and greatest.
