To be fair, River City and Hifi Honey are meant to be early season entertainment and a placeholder for the summer shows.
I will stand by my word and die on the hill, that the park needs to branch out and look for more local bands and not juzt settle with the same 2 bands every year. You can still have them play once or twice, but branch out and look for more like Cedar Point's Bands in Residence Program. There's lots of bands in the local area that would love an opportunity like this. If they can bring the school bands in, I'm sure they can bring more local bands that play at festivals, clubs, etc outside the park.
