Thanks for the replies. I will experiment with the afternoons. May have to cut short mornings or go out later. If i cannot leave and return WMA with same check-in card, will have to take more provisions and use vehicle as "base camp". In my duck marsh, it is always a morning affair as there is no activity in the afternoon. I love reading and napping- i will take that sage advice that if you nap, "keep one eye open"!
