I just found the prelim tag recovery data information on the web last night and today cross referenced that against the records I had for the 400 monarchs I tagged last fall. I was surprised to see that 4 of my babies actually made it to Mexico ! My first time getting monarchs to Mexico. Back in 1996 I had one make it as far as Virginia.

I was wondering what program does Monarch Watch use to determine the mileage distance? Google maps wasn't exactly helpful in that regards and I haven't really found another online program that would seem to do what I want. Three of the tags were recovered in El Rosario and the fourth in Cerro Pelon..... but those are large areas to try and figure out where the best spot to pick to use for calculating distance. Lots of possible locations (different mountains, populated areas, etc. to choose from or am limited to choosing from).
