A Curious Visitor

Hey Everybody,

I'm heading up to Oregon for the eclipse this weekend, and of course I can not pass up the opportunity for some mushroom hunting! I'm not familiar with the state at all, and my girlfriend isn't much of a hiker, so I'm looking for a spot off of I-5 that we could pull off onto for an hour, have a piknick, and poke around a bit.

Does anyone have a favorite spot along I-5 that they could please share?

Also does anyone know where to rainfall data? I thought it was raining recently in Northern CA and Southern OR but I can't remember.

And Thank You!
