I only mention this here because the Humboldt Hot Spots site seems to have gone by the wayside. At least their "Contact" page seems to have. I can get to the main page, but there doesn't seem to be a way to submit a new site.
I noticed, while at the credit union today, that Happy Donuts had a sign on their window saying they offer free wireless internet. I didn't try it, but I'm assuming it works. Happy Donuts is next to Provident Central Credit Union at the Eureka Mall.
GOOO...Happy Donuts, although I still don't see why everyone needs to provide free wireless access.
