From responses by Diverbrian and Mike F, it appears GIlboa will be losing money on this proposition. If there were no winter pass, Brian could be predicted to spend at least $60 for 5 days of diving instead of $50. Mike F. would be spending $36 assuming just one trip for his family. He may have had plans to bring a class at some point as well, but we won't count that. Gilboa just lost $46 on only 4 divers, and we haven't added in any fills.
Add in my group of at least 8 who will not be going next weekend ($96) and then the approximately 12-15 divers who will be making the St. Paddys Day dive elsewhere ($144+) and the rescue class I need to do in April for the local fire department (8 firemen, $96.)
This adds up to 4 trips for myself and probably my husband, so the $50 might look worthwhile to me. However - I don't pay the 2 days I have the rescue class, and if none of the others are diving at Gilboa on the other two days, I won't be, either. I will use the Indiana quarries for this training.
Total lost income just on my group, $382. In the big scheme of things, I have no idea if this is worth it to Mike Williams or not. I'm just sorry we may be losing an excellent winter dive site.
