Thanks VERY much to Elizabeth & Irving Weiss, David Filloy, Lea Samuel & Steve Viavant, Richard Polk, Erin & Mark Mitchell and Robert Clarke for their contributions toward the air quality study. But even with the $1,000 that Barbara and I have pledged, we still have a long way to cover the $4500 cost of the study. PLEASE write a check payable to "Quality Environmental Services" and mail it to Preston Padden at 1301 Canyon Blvd, apt 306, Boulder, CO 80302. We suggest a $100 contribution but checks larger and smaller are welcome. It is a small investment in the quality of the air you and your family breathe. Thanks very much.
