Portland State was the host of Fifth CASCADE RAIN (Regional Applied Interdisciplinary and Numerical) 2018 Meeting, in Portland, OR, and featured a strong representation from Math OSU including former alumni and Cascade ``founding father'' (and designated organizer for 2019) Tom Humphreys. Azhar Alhammali and Joe Umhoefer gave talks, and Lisa Bigler, Diana Gonzalez, Alireza Hosseinkhan, and Choah Shin were in attendance. The poem (among three at https://sites.google.com/view/cascaderain2018/) by the host Jeff Ovall says it all

We imbibed a fifth of Cascade RAIN.

Sampling delicacies both earthy and sublime

some with a complex flavor.

PDEs? Yes, please.

Linear algebra? Positively, definitely.

Data analysis? (Topo) logically.

Statistical techniques? Probably.

Optimization? Nearly.

How did we celebrate afterward?

We plead the fifth.
