Wonder if you ever resolved your dilemma? I know programming via computer/CHIRP is a great way to go. Nice thing about it, if you find someone local (probably several hundred hams withing "earshot" of Madison), they can email you the file for local frequencies.
Field day is coming up and there are a few sites around Madison. We were on vacation there a few years back on field day and my wife and I dropped in on one of the locations. I kind of got a cold shoulder and evil eye reception when I did. Maybe, being local or if you select a different club, you'll get a better welcome. I know the local radio club that I associate with, the Starved Rock Radio Club (W9MKS) welcomes visitors with open arms. My suggestion since you have a week left before FD, do a search and send out a few emails. See who says, "Come on down and bring that HT with you and we'll program it on the spot". Plus, you may get some hands on HF experience as well. When there, roll up your sleeves and be helpful. Lend a hand during set up, meal prep, logging, etc. You won't be "the new guy", you'll be the fellow that was willing to pitch in and help out and likely be included in future events. You'll come away with a whole new perspective of the hobby and a dozen+ new friends. I remember my first field day, probably 1987. There was actually bonus points issued for having a "Novice Station" as 10m had just opened up to novices on phone. First thing I did when the gun sounded was ask, "Is the frequency in use?" My Elmer said, "this is Field Day. Nobody cares if the frequency is in use. Just jump in with both feet." And, away we went!
Let us know how things are working out!
