If you have someone else to do the wader work - set dekes, assist the dog on a retrieve as needed.....you could probably go with boots. But, I wouldn’t. Things can change and I would prefer to be able to get 'wet' as needed.
Funny....back in the 60's, my dad took us 3 boys with him to Wister. We used to wear old pants and tennis shoes and just get wet. The early part of the season was so hot, it actually felt good. He didn't have the money to buy waders for all of us.
Then, we 'graduated' to the plastic waders that Big 5 used to sell (maybe still do). Not much more than a trash can liner these days, but with feet on them and an elastic band to hold them up. I loved it.
Hard to believe it will be my 50th season coming up. God, I would give just about anything to be back there, with dad and my brothers - out hunting.
Go, and have a blast at Wister!
