Regarding the directions to the Arizona Bus Club's "Corona de TucsonII"
event (2/22-23/1997) Near Tucson, Arizona USA.

Good old helpful "Steve S." at steves@indy.net said:

If you haven't found it yet, take the Vail/ Helveta south off 
of I-10 to Houghton, west to Sahvarita, north to Corona de Tucson.
Hope this helps, got it from DeLorme's Street Atlas USA.

Thanks Steve! You are quite the helper. Now maybe I can be quiet about the
event until February! =)
