Oh boy, I'm from Småland so I have tons of info for you, send me an email email@example.com
and I'll tell you what I know. One big caveat to think about, Sweden is 20 degrees north of Knoxville. We are on par with Fairbanks, Alaska so it is still very early in the season over there. If you can delay until mid May it will be like late march in Knoxville weatherwise.
