Does anyone else really like using perception checks involving touch and smell?

These can be easy to forget, but I threw a few of them into my last game and I felt like my players and I enjoyed them and they gave some interesting shape to a few moments. You can give a lot of ominous info through feeling heat/vibration/rhythm on a surface, and smells are so particular that they can become entities unto themselves--I'm planning on all dragons having a very particular and intense smell, for example.

Smell also is a really easy way to drive the behavior of a lot of beasts, since they tend to follow their noses.

Has anyone else found this to be the case and had fun with these?
