There's nothing particularly interesting about Pete's Mountain - it's essentially a suburban pavement activation for one point. There's no public space so one ends up standing on the public right of way a few feet from the road, pretty much in someone's front yard. I was across the street from the actual 'summit' that's in the front yard of a large house.
The road to Glass Butte requires a high clearance vehicle and four-wheel drive is recommended.
The roads in this area to access Little Glass Butte might be Ok in a very carefully driven passenger car, but high clearance is recommended. If you are traveling through eastern Oregon this is a worthy six-point peak to check out, especially along with an activation of nearby G
Sixteen miles of roundtrip hiking, even on a nice bit of the PCT, is a long way to go for two points, but it might the easiest way to get to Buck Peak and it's a lovely hike just the same.
Lava Butte is an easy and fun four pointer if you are ever in Central Oregon. It is a drive-up summit part of the year. There is a sometimes staffed lookout at the top and enough room for operating and most any antenna. Since it is a popular spot, you could get plenty of questions about ham radio when it is busy.
The trail is called the "Starway Trail" but it could be better named the "Stairway Trail" as it is one of the steepest trails I have ever hiked - but the views from the top are worth it. And then, the peak should also have the SOTA vanity name, "Starway." The elevation gain is in the order of 2400 feet in just over two miles and pretty much relentlessly climbs for the first half of the hike. Note that this peak can also be approached from Silver Star (from the south) with less elevation gain, although the trail is a bit faint in places.
See the blog entry for Pine Mountain, W7/CE-058 for details on this activation: www.pnwsota.org/blog/k7atn/2012-september-09/pine-mountain-and-pine-benchmark-or-sep-2012.
Pine Mountain (W7/CN-058) (2 miles RT and 500 feet) and Pine Benchmark (W7/CN-068) (~3 miles RT and 600 feet if you walk the road) are close enough that one could easily do both summits in a day.
Barlow Ridge is a pleasant three mile or so hike (OW) east of Mount Hood with about 1000 feet gain. Although relatively close to Portland the trail is seldom used, (especially past Barlow Butte) and has a nice 'wild' character about it. In other words, the trail seldom sees maintenance. It's a leg stretcher with about 1000 feet of net gain, but quite a bit more elevation change with all the ups and downs along the ridge line. Quite a bit more.
UPDATE JUNE 2018 - Road 27 has deteriorated to the point that getting to the trailhead may prove challenging even in a Subaru Outback. It's certainly unpleasant and rough and slow going. So much so that you may want to hike a few more miles and have an easier time getting to the northern trailhead.
