Just something I noticed if your trying to hatch eggs but not really focusing on it like watching TV while you play. If you go to Mauville and line yourself up with the sign by the pokemon center (the one that says "Mauville City The birght and shiny city of fun") and get on your bike, going either direction you can go free of bumping into trainers or rocks all the way to Vendanturf. Just a little tip.
