If someone can just explain to me what the word “clinched” means in all their posts (does it mean drive the entirety, or do you have the videotape the whole way down the road?), I’d appreciate it
As others have said, "clinching" a road means having driven the entire length. It does not have to be all at once. Most people have their own set of "ground rules" as to what counts and what doesn't.
For example, some roads end at a gate to a military base, or end at an international border, which can be inconvenient. Some people are strict about that, others allow a "sight clinch" - as in seeing the gate while you can still easily turn around.
Or, do you have to re-clinch if a route moves 100 feet to one side (like for a new bridge, or for widening). What if it relocates to an entirely new routing, 25 miles away from the old one?
There are no right or wrong answers!
Also, some people here clinch USA counties as well, keeping track of which ones they have been in. Just driving one road in the county is enough; you don't have to drive every road to clinch the county (unless you want to). Again, everybody has there own "ground rules" about what counts and what doesn't.
Anyway, welcome to the forum!
