Could be sweet, but figure the cost of gas in doing this would be pretty high, that and vehicle maintenance.
but... having a loveland taxi or a berthound taxi could be cool but would make the places either more dangerous because of crowding or because of easier access for noobs with little experience getting their lives ruined on a nice rock outcrop.
I don't know what the laws would be on it either. the county would have some sort of taxi provision written in their laws somewhere that would probably have fees, regulations concerning weather and road service etc...
Keeping it under the table seems like a good idea but in my estimation it would be
$50 tank of gas but probably more due to driving all the way up and back as well
+ insurance and maintenance costs (per day)
Maybe, $60-70 in total costs..
If your buddy were to work a $9/hr job somewhere say 9-5, he would make $72 a day.
Even if it were a 5 hour job, it would be $45... so $60 in total costs plus $45 for a "worthwhile" day he'd need 11 people paying $10 a day.
That said, if he's going to shuttle I'd pay $10 on a pow day.
Maybe he could turn it into a business...?
