If you went on a road trip crossing through the boundaries of multiple CNC teams, and made at least one observation in each area, what’s the highest number of teams you think you could get? Or has anyone actually tried this? How many did you get?
In California a long coastal drive from San Fransisco to San Diego would get you 8 teams–or more if you detoured inland. California is pretty dense with teams (makes sense given we invented the CNC.) What other regions have many teams?
In the US there’s a pretty good 10+ team block in western Oregon/Washington and eastern Idaho. Texas is also very dense, as is much of the US east coast. (Does North Carolina have their entire state covered? Wow.)
In an airplane, you could get birds on the go. That should get a lot of teams.
driving to Kern County tomorrow…I could get observations in Stanislaus and Madera counties this weekend, which, added to Kern and SF Bay Area CNCs, would put me at 4, I think… 
i heard of CNC mashines, what are CNC teams? Oh got you! City nature Challenge… well have fun guys!
Interesting question. I have thought of a related idea of travelling around the world on December 31, hitting multiple New Year’s celebrations as the year in each time zone turned over.
I supposed you could (would anyone want to?) do a strategic world tour on CNC weekend (happening right now) and hit dozens of CNC teams. A big year for CNC, if you will.
I’m going to go for 6. The road trip was planned anyway, I didn’t realize it was also City Nature Challenge weekend.
if you think of contributions in terms of identifications, you could contribute to a lot of teams.
Well said!
I have made a smutty contribution to the Stanislaus County CNC.
This year, I participated in 5 CNCs, within two days and all via bike and public transport.
Was aiming for a sixth one but the weather on the first day was horrible and me being completely soaked I decided for a warm soup instead and to stay healthy for the CNC days to follow
Go fungus! Sterilize that brome!
Now with the ID part finished, I can confirm I managed to make unique observations in 4 different CNC regions.
Realized it is tough to find a rare species when only having a merely 10sec window out of a moving train… (did not make a unique observation for that region 
)
Edit: Just figured, despite not deliberately, I have at least a set of four taxa that make up my unique observations. For each of the four CNC regions, I am the only observer of:
