I used my free year for the trees are good site and got a few calls for service. I am in my paid year now and have received no calls yet this year with customers referencing that site. I will write off the 150.00 as a tax deduction towards advertising. I will probably not renew it again. I don't understand why the main ISA site list CA for free, yet the treesaregood site charges. I did complain and was told about the benefits of additional exposure, and the low cost blah, blah ,blah. I get more referals from my local extension office, that uses the main ISA site as a reference point. I have no intention of dropping the CA, cost more to get it back, I can write off the $125.00 and a few trips a year to the conferences and classes are good learning experience.
