Don't give up !!! As stated keep trying at the hobby shop and call any numbers you can. One other thing you can try is to make up a sign with your name and phone number on it and post it at the field. Making small tear off's for your number might also help. Folks won't remember your number and most don't have pen and paper with them. YOU have to make ALL the effort till you pin them down. Then when you do it will all be worth the effort.
ENJOY !!! RED
