I spent a delightful week in Seoul, South Korea, to attend the MobiSys annual conference. In the process I explored the city, took two hikes, and captured a nice gallery of photos. After the break, a few highlights and observations.

Niagara Falls
The ACM Conference on Mobile Systems, Applications, and Services gave me an opportunity to spend a lovely week in Niagara Falls. I had only visited there briefly, 32 years before, so it was wonderful to have time to explore the Falls from various angles and various times of day. It’s a bit touristy, to be sure, but it’s tastefully done – and the falls are so stunningly spectacular that it is worth visiting again and again.
My photo gallery includes shots of each of the three waterfalls, from both the American and Canadian side, and in both early morning, late afternoon, and at night during the fireworks display. And, even from the Maid of the Mist tourboat that snuggles right up into the misty spray of Horseshoe Falls.

The conference also hosted a banquet dinner at Old Fort Niagara, about 30 minutes north of the falls on the shore of Lake Ontario. The weather was perfect, the sunset beautiful, and the historical re-enactments fascinating. Snapped some fun photos and videos. Worth a visit if you have a chance!

June hikes

It’s been a wet spring, but last week was nonetheless sunny and beautiful – the woods were verdant and full of wildflowers. I had a wonderful hike with a dear friend along the Appalachian Trail close to home, and then four beautiful days to trek around the Mount Washington Hotel & Resort, including the opportunity to take 32 colleagues from the MobiSys conference up some of my favorite short hikes in the Whites: North and Middle Sugarloaf Mountains.

MobiSys in Colorado
Some hiking and sightseeing around a conference in Colorado.
At the MobiSys 2008 conference, which was held at Breckenridge resort in Colorado, a group of us met to celebrate the retirement of Carla Ellis by taking a hike in the beautiful Rocky Mountains. See the trail description and review.

On the way back, I drove over Loveland Pass to stand on the Continental Divide. Gorgeous!
See the photo gallery.
