"your always welcom to hunt the land"
This leads me to believe that he dosn't mind you hunting it but if it were me it would depend on how well I know him. Things can change from one year to the next and if he hasn't said your welcome anytime this year I'd ask. You may find the offer was still good but if the land is good huting it's better to get the land owners respect IMO.
I'd ask again.
