Folks, looking for some input and advise on a roadtrip from SF Bay Area to Portland -- around start of June for 8 days.

• Planning to take Mt Shasta and Ashland on the way to Portland. Heard Ashland Downtown is worth a stop.
• On the way back, Grants Pass and Crescent City to get some of coastal views.

Few questions

1. I saw some references to OR-38/OR-138. Is that a worthwhile detour?
2. I have great memories of Portland related to coffee, trams, parks and bookstores. I keep reading things look different now in downtown for worse. Do I need to reset my expectations. Suggestions on what area to live in (in or around city) to experience coffee, books, parks and lazy relaxing days?
3. Feedback on route above? I would like to see good coastal scenery, beaches or drives along waterways.

Appreciate any help !

I recently swapped to think rider TPU tube (orange colour FWIW) from regular butyl tube. I have never had a puncture in last 3 years using butyl, and after 3 rides with TPU I have a rear flat tire. I’m yet to inspect and see what caused the issue — on visual inspection I don’t see any signs of nails or sharp objects. But I wanted to ask is this the usual experience?

I have to admit, the TPU ride is much pleasant in terms of feedback and comfort. But I can’t see myself changing tubes every other week. Looking to understand if I run into quality issue/bad luck or TPU is a comprise on reliability for comfort?
