I've enjoyed my flights there, but you need to get the approach right. Our club insists on an instructor accompanying you on your first visit (the PA28 shaped hole in the hedge was one of ours, as was another PA28 which landed 15' above the runway!)
The higher than usual circuit seems to throw peoples' judgement a bit, especially if you are used to the length and width of a place like LPL and it's not a field for dragging in low and slow either. If using 22 check for furniture vans, cattle trucks etc on final and there's an interesting tree on the approach for 04!
I've only ever flown there mid-week and there's never been anyone on the radio when I've called. It's worth making blind calls as the last time I visited I was one of five in the circuit.
If you depart to the north-east make sure you know about the masts and cable strung across the mouth of the valley.
Caveats apart, it's a great field to visit.
