GPS Bike GeoGlyph and Zen Pannier Racks

Following up on an earlier post on GPS-bike geoglyphs, and via ForTheLoveOfBikes, we have a Valentine's Day GPS-Bike GeoGlyph by Payam Rajabi for his girl Clare:

I've been seeking advice about bicycle camping, aka bike packing (vs. backpacking), in preparation for what I hope to do this spring and summer.

I've asked about the best tent/sleeping pad combo, and I've been getting a lot of feedback that the best tent isn't a tent, it's a Hennessy Hammock:


I've also been asking advice on other equipment, and I've been given another Zen-like paradox: rackless bike bags. Why carry the weight of racks?



So much to learn, and so much to unlearn.

Ancient Geoglyphs Explained By Baltimore Bicyclist?

PacTom7 is a website documenting Pittsburgh runner Tom's effort to travel over every single bit of paved street in Pittsburgh, running through the city's grid like a PacMan character (hence, PacTom). He tracks every run with a GPS and uses his quest as a tool for continually changing routes.

He produces remarkable artwork with his GPS data:


There is very little new under the sun (VLNUS); using terrain to create artwork that shows up on maps has been around. Geoglyphs are large designs or motifs produced on the ground, typically formed by rocks or durable elements of the geography, such as stones, stone fragments, gravel, or earth. In a way, PacTom's artwork produces virtual geoglyphs.

The cultural significance of the "legacy" physical geoglyphs for their creators is unclear due to a lack of documentation. The 'Works of the Old Men' in Arabia have been described as geoglyphs. Recently some geoglyphs have been discovered in the Amazon Rainforest, in Brazil, among the Megaliths in the Urals. Other areas with geoglyphs include South Australia (Marree Man), Western Australia and parts of the Great Basin Desert in SW United States. Hill figures, turf mazes and the stone-lined labyrinths of Scandinavia, Iceland, Lappland and the former Soviet Union are all types of geoglyph.

The most famous geoglyphs are the Nazca Lines, a series of ancient geoglyphs located in the Nazca Desert in southern Peru. Scholars believe the Nazca Lines were created by the Nazca culture between 400 and 650 AD. The hundreds of individual figures range in complexity from simple lines to stylized hummingbirds, spiders, monkeys, fish, sharks, orcas, llamas, and lizards.


Although there are as many theories as PhD candidates explaining the meaning and purpose of the geoglyphs, there is no generally accepted understanding. It may be that the puzzle of the Nazca Lines has been solved by a Baltimore bicyclist, who has created virtual geoglyphs.

Baltimore cyclist Michael Wallace uses his bicycle and his GPS to make the streets of Baltimore into his own canvas by planning, riding and tracking creative routes.
