Hi Zack,
This works as expected on my machine:
tank_trunc <-
read.csv("http://r.789695.n4.nabble.com/file/n4492267/upton_tank_trunc_nabble.csv";)
michigan_map.df <- map_data('county', 'michigan')
ggplot() + geom_point(aes(lon, lat), data = tank_trunc, na.rm = T) +
geom_path(aes(long, lat, group = group), data = michigan_map.df) +
coord_map('gilbert', xlim = c(-88, -82))
