Camp Perry, located on the shores of Lake Erie is an Ohio National Guard Training site that has exceptional facilities for Highpower Rifle competition. Thousands of shooters from almost every state and several other countries travel here to compete. It is often intimidating to new shooters to shoot for that first time. Most anticipate that they will be surrounded by great shooters and they don't feel capable. This isn't true at all.
Most shooters are very helpful towards helping new shooters.
Before jumping head-first into highpower competition, I suggest that you attend a match to get the feel for how it is ran and what exactly goes on. Talk to people and get to know them. Introduce yourself as a new shooter and ask them to explain anything that's not clear to you. If you aren't sure where a match is near you, your best bet is to ask around at a local gun club, or contact your state's Rifle and Pistol Association. Most active shooters in gun clubs will at least know someone that shoots highpower, or a range that holds matches.
