I want to catch "her"

Some of you may have seen my post yesterday about my failed attempt to rescue this stray (http://www.thecatsite.com/forums/sho....php?t=103876). I want to go back today and start to feed her and hopefully catch her but I have 2 problems:
1) the Humane Society (about 100 feet from where I found her yesterday) said that they would feed/catch her, but I'm not sure if they will since it took my FI 3 times telling them there was a stray outside to get them to open the door yesterday (they were closed for vet day, but there were still a ton of people there)
2) she likes to come out in the open space but as soon as she sees a carrier or trap, she bolts so I don't know if I could drive up near her and grab her (hopefully more successfully and with long sleeves on) and put her in a carrier that's hidden in my car or if I should just bate a humane trap (which I'd have to get from the Humane Society) with food b/c I know she's very hungry.

Any advice? I was going to call today and tell them that if they catch her and she's not claimed then I'll foster her to resocialize her but I'm worried they'll just blow me off.

i caught cats in carriers and in traps and sometimes its just a
judgement call. maybe try the carrier first and then if that does
not work the trap. you will have to cover the carrier (except for
the door) so she does not see you walking towards the carrier
to close the door or you will have to cover the carrier and rig
up a rope to close the door with.

good luck !!!

what state are you in ?

I'm in Indiana. I went last night, after the humane society closed, to try and feed her but she was nowhere in sight and didn't come out for food. I left the food near where I saw her hiding and will call the HS today to see if they caught her.
