Here's the big event happening in Indianapolis:
Indianapolis Boat, Sport and Travel Show Feb. 17-19 & 22-26, 2023
It's more than just campers, it's everything sportsmen related. It's always huge. You can run through it all in a day if you walk as fast as you can. But if you really want to look at stuff, you really need to take a couple days.
They include Indiana DNR demonstrations, usually have a fishing pond for the kiddo's, every kind of bait and tackle shop located east of California! Resort rentals, house boat rentals (like Dale Hallow in Kentucky) and a bazillion others. Everything from canoes for sale to gigantic house boats. Everything from tiny tear drop trailers to million dollar motor homes. Every kind of camping gadget imaginable to humanity can be found there. As well as demonstrations on almost anything "sportsman" related, events, shows, and special activities for folks of all ages.
If you've never been to this one, make sure you bring your wheel chair along. By the end of the day, you'll be so exhausted you'll need to be carried out. And oh ... bring a utility trailer with you to haul all the stuff you buy back home too!
