[ILQSO] Operating Question

[Tim N9PUZ]

I plan to operate in the IL QSO Party this weekend but I haven't made 
a decision as to "how" yet. Is it permissible/legit to:

Operate with the Sangamon Valley Radio Club portable operation at 
Sangchris State Park in the afternoon and then operate from home in 
the evening?

Would I let my contacts at the lake be submitted with their W9DUA call 
and then submit a separate log under my own call for evening operation?

or...

Do I need to just pick one location or the other?
