I built a tower stand, mainly for taking the kids. The platform is 6'x8' and we have regular stairs built for it. We can talk, they can play games, snack, stretch out to nap, move around, and we put a Buddy Propane heater in there too. Works out great!
When the kids got a little older (10 or so), I bought two man ladder stands. Bought them each a HSS and have HSS Life Lines to hook up to on each stand. They are secured from the time they step foot off the ground, until they step foot back onto the ground. Of course, I also followed right behind or in front of them too. Nice to see them years later and the HSS and Life Line use is "second nature" to them now, as I never have to remind them. Then again, they saw what I went through with my tree stand fall and surgeries, so that's a good reminder for them too!
