<br>
I'm not trying to say I'm opposed to removing these. I was trying to<br>
ask if we know how this data relates to current MassGIS data and what<br>
that means. So far, I don't understand that, and thus I don't feel that<br>
I can have an informed opinion about the situation.<br>
<br>
It may be possible to separate actual parcels that protect water<br>
supplies and these zones. The former seems legitimate and useful, and<br>
the latter much less so.<br>
