Just spent 2 hours looking for a 5k race at Main Park in Mokena, IL. Google actually gave me not one but two bad locations.
The second bad location was a different park, where a local was able to give me good info. Another person there mentioned that others had come before me, looking for Main Park.
Got to Main Park with a little time to spare, but the parking lot was full. Plenty of police, but no sign they knew their lot was full. Was directed to park about a quarter mile away, but by then it was simply too late to make the start.
Mapquest, to its credit, does know the right location.
It turns out that the organizers gave the address as being at 10925 LaPorte Rd. Google needs the address to be La Porte Rd. Otherwise Google sends you to Francis Rd.
If you give LaPorte to Google without the space
it turns out you're in danger of missing the race.
