Welcome to the site! Read up, watch YouTube videos, but be aware...them videos make hunting look a whole lot easier than it really is! I hunted public land here in NE for four years before I tagged a Muley.
Find a state and an area you feel comfortable with, tags you can purchase with minimal points, or over the counter. Get the right gear -- lots of lists on this site. Search and enjoy. Get the best gear you can afford...buy once, cry once.
Get boots on the ground. Log your hunts, make lots of notes of the area, things that worked, things you observed, hunters you talked to, etc.
Have fun, and post your questions and stories here. Great place to learn and share!
