I know about the fairground RV setup, but never stayed there before. Couple of nice looking RV camps on highway 50 just west of town. Frontier is a good idea. Wish I'd thought about them when we shopped next door at Big R couple of weeks ago. If they have some, I'll call and pre-pay, pick up when I get there. 1F is best, but in a pinch can use 2F. 2F makes for a different flight path for the 1" ball bearing, thinking same charge of 1F gives a little more speed, could be more pressure in that size bore.
