 Grant was one of the first anglers to realize that large trout fed primarily beneath the surface on nymphs, and that one needed to imitate and learn to fish this insect-stage if one wanted to consistently catch large trout.Grant's nymphs imitated primarily large stoneflies such as the giant salmonfly ("Pteronarcys californicus"), which grows up to two inches in length.In 1973, the Federation of Fly Fishers awarded Grant the Buz Buszek Memorial Award-an award plaque presented annually to that person who has made significant contributions to the arts of fly tying.
