US 17 and US 98 in Fort Meade, Florida.  June 28, 2008.



Another US 98, along with US 27 and Alt US 27 in Perry, Florida.  July 25, 2024.



I'll play another US 17/US 278 in Ridgeland, South Carolina, only because it is a chance to have Switzerland in this thread.  June 21, 2008.

US27 and US68 in Paris, Kentucky


KY-US68-1973EWR by Paul Across America, on Flickr

Those are the only two I can think of. 7/8 might be the worst of the odd/even challenges.

The remainder of June:
June 24: Post the junction of a US highway ending in 7 and a US highway ending in 9.
June 25: Post the junction of a US highway ending in 8 and a different US highway ending in 8.
June 26: Post the junction of a US highway ending in 8 and a US highway ending in 9.
June 27: Post the junction of a US highway ending in 9 and a different US highway ending in 9.

Then we enter July posting US highway numbers based on the tens digits. We start at 0,0 as always. So on July 1, get ready to find intersections of two US highways where both US highway numbers have a 0 as the tens digit.

And my 8-lessness means I'll see everyone again on Friday!
