i have homing pigeons and rollers, some i fly and some i keep up
i can take my homers 25 miles down the highway and turn them loose and drive 65 mph home and they will be in the tree tops when i get there
of course you don't take them 25 miles the first time and if the road was straight i might beat them home
i have taken them 75 miles away and they come back
my friend in central Arkansas has taken his to Oklahoma and they come home
