Hey all, so awhile back i asked helped on the trigger Geolocation functionality to google. I found the information i need to create a trigger to google from

http://blog.internetcreations.com/2012/09/creating-a-geolocation-trigger-in-salesforce-winter-13/

and everything works just fine now. But I am having a hard time bulkifying this code. Can someone help me?

trigger trgGeoCode on Address__c (after insert, after update) {
    
    List<Address__c> addList = [select id, AddressGeoLocation__Latitude__s, AddressGeoLocation__Longitude__s 
    from Address__c where Id IN: Trigger.newMap.keySet()
    and Account__r.Type__c includes (: 'Facility') ];
    
    for (Address__c a : addList){
        
        if (a.AddressGeoLocation__Latitude__s ==null ){
            ClassGoogleGeoLocationCallout.getLocation(a.id);
        }
    }
}

 and my main class stays the same based off the blog:

public class ClassGoogleGeoLocationCallout {

@future (callout=true)  // future method needed to run callouts from Triggers
      static public void getLocation(id addId){
        // gather account info
        Address__c a = [select Name, City__c, State__c,Zip__c, Latitude__c, Longitude__c, Country__c
        from Address__c 
        where id =: addId]; 
         
        // create an address string
        String address = '';
        if (a.Name != null)
            address += a.Name +', ';
        if (a.City__c != null)
            address += a.City__c +', ';
        if (a.State__c != null)
            address += a.State__c +' ';
        if (a.Zip__c != null)
            address += a.Zip___c +', ';
        if (a.Country__c != null)
        address += 'USA';
 
        address = EncodingUtil.urlEncode(address, 'UTF-8');
 		system.debug('=== ADDRESS ===' +address);
        // build callout
        Http h = new Http();
        HttpRequest req = new HttpRequest();
        req.setEndpoint('http://maps.googleapis.com/maps/api/geocode/json?address='+address+'&sensor=false');
        req.setMethod('GET');
        req.setTimeout(60000);
        
 
        try{
            // callout
            HttpResponse res = h.send(req);
 			System.debug('====RESPONSE====' +res.getBody());
            // parse coordinates from response
            JSONParser parser = JSON.createParser(res.getBody());
            double lat = null;
            double lon = null;
            while (parser.nextToken() != null) {
                if ((parser.getCurrentToken() == JSONToken.FIELD_NAME) &&
                    (parser.getText() == 'location')){
                       parser.nextToken(); // object start
                       while (parser.nextToken() != JSONToken.END_OBJECT){
                           String txt = parser.getText();
                           parser.nextToken();
                           if (txt == 'lat')
                               lat = parser.getDoubleValue();
                           else if (txt == 'lng')
                               lon = parser.getDoubleValue();
                       }
                       System.debug('====LAT====' +lat);
 
                }
            }
 
            // update coordinates if we get back
            if (lat != null){
                a.AddressGeoLocation__latitude__s = lat;
                a.AddressGeoLocation__longitude__s = lon;
                update a;
            }
 
        } catch (Exception e) {
        }
    }

 So in the end when I try to bulk update using dataloader i get an error saying:

System.LimitException: Too many future calls: 11.

Thanks for the help
