@Brian Mulligan hit me up about this and music business:)

But seriously, we crank up the music, get on our safety gear, fire up the tools and have fun .... and we know that mistakes are also deep learning lessons.  

I was thinking of splitting the the two parks .. rv will Have their own community and BBQ area and the motorcyclist willl have cabins and tent areas across the way  .. that being said I will have an amphitheater in the middle for bluegrass and blues music on the weekends for all ... does anyone else here have anything like this or am I way off base to combine the two

If they have more expensive possessions or need riders for specific items (one guy had a few high end musical instruments) it can end up higher.Speaking as someone that had his place broken into by 'friends' while young and renting, I wish I'd have had a renter's policy.

I also write music for TV/film/video and generate a modest supplementary income from that, but I want to have a cash flow to fall back on/fund bigger and bigger deals. 

If you mean construction cost, the elements of that line item alone is composed of two major sub-line items being hard cost (slab up) and site work which is further bifurcated into on and off site costs.

The food, art, music, craft beverage scenes are all flourishing as well.

I'm just starting out in real estate and real estate investing and I'm anticipating doing a fair amount of driving. as much as I love music, I know that my time behind the wheel would be better spent listening to audio books. that being said, any recommendations?

Play your own music.

The city council is also going to vote this evening on allowing for a 5 year contract for Superfly Productions to take over Overland Golf Course for 5 weeks (think Coachella Music Festival).
