Just look any where you see crystaly, stickey, stinky bud. Them crystals are your tricomes. Little tip, save your trim and dry it, when dry, run it over a real fine screen with a credit card. The keif that falls through is great for cooking or just to smoke. Its basicly the tricomes that were forming on the trim/leaves. The finer the screen the less leaf falls through so it would make a better smoke.
