Pros: - Permanent concessions - Tifos and video boards - Consolidated (?) bleachers may create a more cohesive unit of supporters Cons: - We need more instrument players in attendance again - Any mention of permanent restrooms - Bleacher sight-lines www.forwardmadisonfc.com/news/2026/09...

My favorite aspects of Madison’s are the button-operated space heaters above the benches, the wood ceilings, and the views.

You, too, can spend your free time exploring Lidar maps for the state of Wisconsin: data-wi-dnr.opendata.arcgis.com/maps/f2e49a4...

Verona, WI has a prominent road named Nine Mound Rd. Suddenly curious about its origins, I went to some old plat maps (1873) showing 9 burial mounds in what is now the campus of Epic. Even better, Lidar maps still reveal some of these mounds very clearly.

"Epic has since protected the rediscovered mounds, and their horticulture team has planted native prairie plants in that area.  They are no longer "mounds", but it is good to know that this important and sacred link to Verona's early inhabitants is finally protected."

The test did not go as planned (it capsized). But that’s what I love most about it. I was seeing the iterative engineering process hard at work - knowing one day, four human (and a stuffy named Rise) will depend on the data collected from moments like this. 📸 NASA

With #Artemis II splashdown in the books. I wanted to share a memory from 14 years ago. What you see here is my view of the Orion capsule drop test performed on November 8th, 2011 at Langley Research Center in Virginia. I was invited to come as part of a #NASASocial program.

It seems there's some movement on this issue. Crews are out this morning removing the deteriorating red paint that was installed by Zenith Tech. Unsure if this is being done under the contract's warranty or not. We'll have to see whether the same methyl methacrylate compound will be used again 👀

5/ Some notable ones include adding bike/pedestrian priority at Main St/Verona Ave (🙌), connection to Verona Ave from existing path terminus near Badger Ridge Middle School, separated paths along Basswood to Sugar Creek Elementary (iykyk) and completion of path along the length of Verona Ave

4/ Active Transportation - I mentioned previously, but there is a generally substantial expansion of trails and multi-use paths across the city.

3/ It's also worth mentioning that this proposes the re-zoning of the highly car-centric commercial land abutting E Verona Ave into mixed-use downtown and neighborhood. Consider this with the existing Festival Foods and new all-day bus service to the area.

Mark Liederbach @liederbach.dev · 16/09/2025
2/ Of the targeted subareas, the all-new East Neighborhood is by far the biggest, with a grid that would extend from the current terminus of E Verona Ave. It would consist primarily of mixed-use and mid-density housing. BTW, green dotted paths represent new trail connections.

1/ First, land use. The plan highlights the expansion/establishment of neighborhoods to the south and east of the current grids, as well as an expanded downtown subarea. In total, an est. increase in housing capacity of ~23k over 30yrs in these areas specifically.
Population growth capacity by subarea over the next 30 years.

Just me at a crosswalk
Busy crosswalk in Madison, Wisconsin at the intersection of John Nolen, Williamson, and Blair. One of Madison's most notorious intersections, known for accidents, confusing patterns, and trains.

On the signal pole, a sticker reads "1 in 3 drivers admitted to running a red light in the last month. Careful out there!". In the crosswalk, an ambulance happens to be going by.
