How drive-time warnings work
GigTools warns when an act's next or last gig is too far away to drive between the shows in time.
Up to date as of GigTools version 2.1.75
When an act on a gig has another gig within a day or so, GigTools checks the distance between the two and the time between the shows. If the drive looks longer than the gap (plus half an hour to spare), the gig page shows Tight travel, with the other gig, the rough driving time and miles, and how long there is between shows.
It's a rough guide: distances come from the ZIP code or city of each gig (or its venue), at about 55 mph on the road. Gigs closer than 30 miles aren't checked. Gigs at overlapping times also show the Scheduling conflict warning.
Fill in each gig's city or ZIP (or its venue's) so the check can work.
