Please use Revolving Door

There is a certain workplace in downtown Portland that anyone who is familiar with it will instantly know what I am talking about. It is a large workplace, and at the entrances there is a revolving door between two regular doors.

There are large signs on the regular doors that say "Please Use Revolving Door". This is because a revolving door does not let in heat or cold the same way a regular door does. When you open a regular door there is a large breeze of air that comes through, and it is very inefficient from a heating or cooling standpoint. A revolving door in contrast, is never really "open". At any point in time two if it's "arms" will be in contact with the walls, allowing it to maintain a "seal".

Well I think a very interesting study in human nature is these doors.

Fully 50% of the people I observe walk through the doors with the big signs on them saying "Please Use Revolving Door".

If I had the time I would sit there with a clicker and count actual numbers. But I am pretty sure that they ALL don't have a revolving door phobia. (If so I think we should start studying that because it would be more common than almost any other phobia that exists!).

Strange. Maybe it is not for me to understand.

Cascadian automobile crashes - by the numbers

Here is a real interesting counter. You can look in "real time" how many people and how much money is lost due to automobile crashes in the Pacific Northwest (Washington, Oregon, Idaho, and British Columbia). Car Crashes, By the Numbers (counter)

Free Topographical Maps

The Libre Maps project has purchased and made available for free all of the USGS Topographical maps of the USA. All 50 states. The maps have always been free sort-of, there was just no where until now to actually GET them for free. The Libre Maps project raised enough funds to buy the many gigabytes of data and the Internet Archive is hosting them. These are great 24k scale topographical maps folks. The same types you pay for in sporting goods stores. And many applications on your computers can work directly with them and your GPS. You can get water and tear resistant paper and print them out.. All good stuff... For the lazy in the audience, here are Oregon's.

Why shooting should be banned on public lands:

I don't need to say too much. The pictures speak for themselves. These pictures were taken at ONE spot on NF-45 forest road in Mt. Hood National Forest. The road is also known as "Memaloose" or "Maymaloose" road depending on which sign and map you read. It is maybe 50 miles outside of Portland, southeast on Hwy 224 - along the Clackamas river. The country up there is some of the most beautiful scenery on the planet. The ridge lines, and the deep jagged canyon from millions of years of raging water in the Clackamas river are something wonderful to behold. Driving up this road, we passed at least 5 spots that seemed to be popular with shooters, before we turned around. The road is a steep one lane paved road, and our GPS said we went from 700ft. at the river to 3000ft. almost instantaneously. At some points there are steep 1000 foot drops on either side of the road. It is breathtaking. Until you come across the shooting sites, which make you nauseous. I ...
