Heard Mcminnville is a really popular spot for the locals. The drinks are nice and I am sure you will find the people there to be interested in the same things that you are.It is a nice little spot that might go unnoticed, but it might just be the place that you are looking for.
If you are looking for some cool places to go smoke weed around town then you can check out Olde Stone Village which is a really fun place to hang out. You could also try Discovery Meadows Community Park which has many cool walking paths and places to chill in the natural environment. It is always nice to smoke weed in the great outdoors and in this state there are many options to choose from at all times.
