Oh man, I would have had a huge crush on you

Internet cafes! I used one, once when I was on vacation and needed to submit something for an online class when those were new. Ok, now I feel old lol

You can call the elementary school closest to you. They might tell you to call the district office. They will tell you what to do. Usually, you can fill out registration paperwork and scan documents (immunization records and proof of address) and upload them online on the district's site.
